Anyone else notice packet loss / traffic on their TBBG over the last few days, even when computers are off?
(http://www.thinkbroadband.com/ping/share-thumb/631587e2f0df3402aed9eafa610bb5da-05-11-2012.png) (http://www.thinkbroadband.com/ping/share/631587e2f0df3402aed9eafa610bb5da-05-11-2012.html)
I had some this morning which completely buggered my connection. I noticed before leaving this AM that the met office app wasn't working but only realised it was my connection when a stream of emails came through late morning (I've got my own server).
This evening watching iplayer via freesat I had to disconnect and reconnect to get it to play with constant buffering. However, it's been fine since doing that.
My connection is FTTC btw.
I've not seen any significant packet loss but I have had a lot of buffering on iPlayer, Sky Player and ITV Player during the last few days. In fact iPlayer often fails with a insufficient bandwidth error. I've run tests and my connection appears quite healthy so I assumed it's a server side capacity issue :dunno:
Having looked at the staff TTBQM 3 FTTC users are showing a small amount of packet loss between 8-11 last night and an increase in the maximum latency.
So it looks like IDnet side that's slightly congested?
On my one, between 3pm & 10pm my connection was hardly used.
Not necessarily Paul as they are the only TBQMs I currently have access to and of course they are all with IDNet , I can't find any non IDNet ones at present.
Yes, as attached:-

Thanks Joe that's the same as the ones I've seen,however there is one FTTC IDNet customer TBBQM (Bill)not showing anything in the way of packet loss or an increase in the maximum latency, that implies to me that perhaps BT is involved, it would be nice nevertheless to see one from a non IDNet FTTC customer though.
psp83,
My latency used to be as yours but increased some time back to its present position. The packet loss 'chatter' is becoming more frequent as are the bigger packet loss happenings. I sometimes doubt my Fritz!box and ponder returning to OR modem but then decide that the uptake in local FTTC connections is a more probable cause. It was obviously better in the early days when one was sharing the cabinet with few other people.
Hello,
Just registered to say that I too am having the issues mentioned (packet loss and an increase in latency). I'm on an ADSL2+ package with IDNET, I don't have the thinkbroadband line monitor but I'm experiencing very slow browsing and lots of time outs when pinging using the command prompt. Pings are up to 48-51ms when I usually get around 25ms. No sign of trouble on their network status page http://idnet.net/support/networkstatus.php (http://idnet.net/support/networkstatus.php) I hope this gets resolved soon.
edit: Thanks Simon!
Not as fancy as the line monitors but this is what my connection is like at the moment:

My ping always changes, one week it will be 13ms, another it will go up to 27ms, but always below 30ms.
All depends if its the right type of rain in the air, the direction of the wind, if the neighbour got out the wrong side of the bed, etc etc ;D
Other than this issue at the mo, my connection is normally fine, I don't really get any packet loss and the green/blue/yellow line is normally flat (unless connection is being used)
Yup, just came here to ask if anyone else had seen it. I'm on FTTC with typically 76Mb/s throughput:

That's on the Banbury (Brackley) exchange.
I did a speed test around 6pm (the spike) and browsed a bit on and off without any problems though. For me it's just curiousity as it didn't impact me at the time. A more typical evening for me is:

I'm connected to the Inverurie (NSIUR) exchange.
:welc: :karma: caber
Another first time poster here. I'm also suffering sudden and drastic packet loss. I'm in Inverness. Reported to IDnet this morning 30 minutes after the problem suddenly appeared. Line test came back fine - modem is synced at 11576kbps down 1100kbps up. Checked the AAISP status page and they have a note that the Falkirk RAS suffered a blip at 10:15 am this morning with resultant packet loss. I'm assuming this has affected everyone north of Falkirk? How to put a rocket up BT's bum?
Nothing mentioned on BT service status page. When it first happened I powered off the modem for 15 minutes or so and when turning back on, could only connect to BT wholesale service page - router had a generic 172?.x.x.x BT IP rather than an IDnet one.
Why do AAISP have such a great service status page and why don't other ISPs follow suit?
IDnet support say nothing wrong with line, nothing from BT saying a problem. Told them about AAISP service status page and have been told to keep an eye on it. I'll be phoning back if it is not better by 5pm so that IDnet can escalate to BT - my business depends on my connection! :mad:
Edit: Zen internet status page shows problems with exchange in Edinburgh since 10.20am.
:welc: :karma: Toad
I did see that on AAISP and was going to ask caber how long he'd had the problems for as he's north of Falkirk as well . Obviously we've no idea on the mysteries of BT's routing.
Thanks for the welcome Steve :) - another interesting service status post from Plusnet (wholly owned subsiduary of BT and yet BT don't mention it - :-\ ) - seems BT works could be affecting the whole of UK, even though most work is supposedly carried out overnight. Quote:
"Planned BT Network Maintenance - Week commencing 5th November 2012
05/11/2012 @ 17:03
When's this work happening?
Early hours of most days this week.
What does it affect?
Broadband connectivity.
How long will it take?
Up to six hours each time.
What does the work involve?
We've received notifications from our suppliers about maintenance work that is scheduled to take place in the following areas this week. This work typically takes place between Midnight and 6am.
6th November
Walsall, Kingston and Fulham
7th November
Preston, Nottingham and Dorchester
8th November
London Faraday
9th November
Birmingham
Although these are the areas we have been notified of, due to the nature of the broadband network these outages may affect customers nationwide. There are also a number of smaller exchange works most nights of the week that may cause smaller outages at individual exchanges.
Am I likely to notice the work?
Yes, there's a chance that you may be disconnected from the internet for a period of time during the maintenance window.
Is there anything else I need to know?
Any end users having problems connecting once the maintenance is complete are advised to log into their router interface and click connect.
Kind Regards,
Chris Purvey
Customer Support"
Connection on and off here in Perthshire since 10:16 am. This logon took a minute or more to load. Done manual loggoff/on to break session. No luck.
Thanks Steve,
Good catches with the exchange faults toad, I've given up trying to browse sites at the moment as I don't have the patience for it when it's as painfully slow as this. It was around 10am this morning that I too started experiencing the issues.
I wonder how long before BT declare it as a fault? The only currently declared BT fault is in N.Ireland.
I'm in Ayrshire and my connection is terrible. Can't download email and it took ages to access this forum.
Other websites are just as bad.
BT's Lack of Performance Tester tell me I now have a download speed of O.12 Mbps. Even for rural Scotland that is a touch on the low side. Meantime we endure BT's endless infinity advertising, which would be best spent on replacing the cocoa tins and string that is called BT's network in Scotland, which they say is within acceptable limits.

Fault, what fault? "Performance is within acceptable limits."
:no:
I can understand the frustration. I can also understand that BT/Openreach have a job trying to maintain/upgrade the network in the face of cable thieves and an archaic infrastructure. Most of the time I'm perfectly happy with my ADSL2+ service however what I am not happy with at all is the apparent lack of concern and dissemination of information by BT/Openreach. Customers should be given ample warning of the possibility of network problems if major works are going ahead. ISPs using the BT infrastructure should have an active and ongoing technical dialogue with BT so that this information is readily available. How long does it take for them to admit to a fault. Surely they have some kind of realtime monitoring equipment?!!
With regards to rural exchanges; what boggled my brain was the fact that for a lot of these exchanges, all the data and voice of entire communities is relayed across the hills via peer to peer microwave dishes! And there was me thinking each exchange had fibre or cable or something.
"Infinity", huh, yeah, that is about the length of time it will take until everyone benefits from it.
All seems to be fine again for me.

We're just got back from holiday yesterday and our connection has been atrocious. My IP Profile seems to have dropped from ~6Mbps to 1.75Mbps and since earlier this morning it's been virtually unusable. The BT Speedtester gave me download test of 0.05Mpbs!!! :o :bawl:
I though it was just me so I emailed support, but it seems to be too similar to what's being reported here to be a coincidence. Hopefully we'll get answers soon.

I'm pretty sure
it is a coincidence. A lower profile normally indicates a low sync event which is local to your line and/or exchange.

Yeah, that's why I went to support first. The 0.05Mbps download speed seems to have resolved itself and I can get closer to what my current profile would suggest. I've asked Support if they can reset my profile so we'll see if that makes a difference, however the router seems to be reporting higher attenuation than I was seeing previously, so it's likely there may be a line issue somewhere between myself and the exchange (which will quite likely be a very painful process to resolve).

I'll have you know that is state of the art microwave technology, or it was when the rest of the UK had it installed in 1962, along with the Euston Road Post Office Tower, now decommissioned in favour of fibre.

A friend of mine, a computer engineer, was recently sent to a remote part of Skye, to deal with a very irate man who had bought a computer but it would not connect to the internet. My friend asked where the broadband connection was and the customer said he did not know if he had it. So he asked the man where the phone was. "That would be in Dunvegan," came the reply.
;)
Meantime, the problem I did not have because my connection is "within acceptable limits" for a cocoa tin and string, seems to have gone away.
:fingers:
Got home and it seems my connection is underperforming. It's not time for its bi-monthly stupidity and the TBBQM graph doesn't look that either but it's not giving it's normal speeds either.
Well in the last 30 mins I can see 4 FTTC TBBQMs showing a small increase in max latency and evidence of packet loss.
Quote from: Steve on Nov 06, 2012, 17:29:59
Well in the last 30 mins I can see 4 FTTC TBBQMs showing a small increase in max latency and evidence of packet loss.
I've just powered my router off for 20 minutes and now things are back to normal. No idea if that's my 'normal' problem occurring outside of it's normal bi-monthly cycle or just that last night's glitch produced the same kind of symptoms.
:dunno: Just wondering: could the slight increase in latency between 4pm and 11pm be related to increased on-line activity generally now the clocks have gone back, on the assumption it takes us all about a week to adjust our behaviour and the nights draw in to the late afternoon? It doesn't look like I can compare with last years TBBQM, and probably it won't last anyway when we have other things to do . . . And with the rains followed by frost isn't it going to put the (weaker bits of) local physical infrastructure under a bit of (atmospheric) pressure?
Maybe but I'm not doing anything more in the evenings than I ever did. I'm seeing more latency and packet loss than normal tonight as well although since the reboot my speeds seem fine.

A more typical day's usage:
(http://www.thinkbroadband.com/ping/share-thumb/93b9b8974c7ff0cd354b638e03bd974b-01-11-2012.png)
As you can see there's normally a slight increase in latency in the evening but barely noticeable (the spike at 4pm will have been a speed test).
So usability is not affected for me but I'm curious - something seems to have changed.
I think that's it I am curious as well. I'm see a sustained rise in maximum latency on a quiet connection, it's unusual to see any changes to this on FTTC unless a continuous download is occurring (unlike adsl) conversely I can see 2 adsl2+ lines which are showing no sustained rise in maximum latency this evening.
Is everyone still seeing this?
For me its now happening between 4pm - 10pm

I can see the same on 4 out of 5 FTCC admin connections, the ADSL lines don't appear to be affected.
Yup I'm still seeing it. Quite a bit of packet loss on occasion. Doesn't impact anything though.

Looking at that graph we should bear in mind that the house was empty until 4:30pm. There's a mail server but it's not doing much at the moment.
Edit: I stand corrected. My throughput is poor tonight - barely getting above 30Mb/s.
That's exactly what we're seeing on the staff side- shall we blame the Tennis I wonder?
Well IDnet are saying they've heard nothing from BT about congestion on FTTC connections :-\

Gotta be something going on somewhere.
I'm also only getting 25Mbps down when it's normally around 60Mbps.. Websites are taking longer to load as well.
(http://speedtest.net/result/2296959512.png)
My throughput has been a constant 37.4x Mb/s for months, it never wavers. I've just run a few speed tests and the best I can get right now is from BT @ 21.2Mb. There's also evidence starting to show of some not insignificant packet loss on some of the staff BMQs. Others are completely clear which I can't explain.
So yeah, in short, things are not so good for some of us right now.
mine is as per andrue and psp83:-
(http://www.thinkbroadband.com/ping/share-thumb/246f94c1ac0bc68046464f875a5bcba2-09-11-2012.png)
net has appeared generally sluggish yesterday and today.
Just done speed test (Speedtest.net) Milton Keynes 27.56/16.16 and London 39.06/16.06
Normal service 62.90/17.29
Something is not right!
. . . same as everyone else, though in my case its 4pm-just past midnight and even when the connection is not actively in use. Mid-evening though a speedtest.net test gave me a best-ever max of 45Mbps on a 40/10 service. Averages though on regular testing using JDasts auto-tester (usually consistent) are fluctuating wildly, with a few as bad as the early days of ADSL with pings of several hundred. TBBQM is showing up to 5% packet loss. Somewhere beyond the cab, it seems, from the router monitoring data which is OK.

My throughput has now recovered to it's full 76Mb/s. There's clearly some'at going on.
also back to normal:-
(http://speedtest.net/result/2298154964.png)
There is definitely something wrong. I have been seeing slow web pages (30 seconds to 2 minutes to load simple pages, with some timing out) and stream rebuffering (Netflix, Eurosport, BBC) for the last few days, but the BT speedtest shows 65Mb download which is normal. However its showing 5Mb upload which is usually 10Mb.
Chris
When you run the BT speedtest what is the throughput figure achieved during the test, is it 65Mbps?
Download average 65Mb, line profile 77Mb. This is how it always has been.
Upload average 4.7Mb, line profile 20Mb. This usually averages 10Mb.
I would have said congestion if the throughput was affected.
As has been said try a reboot of the router and then try again (it won't affect the profile as you aren't touching the modem)
People here put a lot of faith in TBBQM graphs but they can be affected by load on the connection between IDNet and Netconnex who host and own Thinkbroadband

That's true although:
1 thinkbroadband-gw2.core-rs2.thdo.ncuk.net 5 5 1ms 2ms 2ms
2 gi4-47-10-star1.bdr-rt3.thdo.ncuk.net 5 5 0ms 12ms 57ms
3 idnet-gw1.thdo.ncuk.net 5 5 0ms 0ms 0ms
4 telehouse-gw4-gi0-1-400.idnet.net 4 5 1ms 1ms 1ms
5 ****.me.uk 15 15 11ms 11ms 12ms
There's not many hops there. It isn't even going through LINX. I'd be inclined to say that is likely to
understate latency.
Normally with congestion the minimum latency should rise, also in a congested connection the throughput drops off quite dramatically. I've seen no evidence of this at all, something is odd but what I've no idea.
Gone very naff again:

I've emailed support again, something has to be going on somewhere, either with BT or IDnet.
Rik's ADSL line is showing it too, but his LLU line is fine.
It is? I must check. ;D

Bill is keeping quiet, so I blame him for taking all the bandwidth! :evil:
I just noticed, on mine and zaps it both started around 10am today.
I've not really used the connection heavily today, just a few uploads as most work has been done to my local server.

Mine too and no-one in the house until later in the afternoon. Mail server logs show nothing out of the ordinary - just the usual trickle of half a dozen spam messages going in the bit bucket every hour.
Don't know if this helps or not but my FTTC connection has shown no signs of slow throughput or packet loss, I'm based in the Midlands. So it sounds more like BT based rather than idnet.
I wonder if this is the cause of the problems http://status.aa.net.uk/apost.cgi?incident=1627
Geographically for me that link makes no sense but who knows.
I fixed my issue. Rather stupidly I had 2 devices with the same ip address, so they were constantly dropping connection. :slap:
I copied the settings from my android phone to my new android tablet, including the static ip address. Doh!

;D
How many BT backroom staff does it take to correct a speed fault?
None, they just declare T1 the new standard.

(http://www.speedtest.net/result/2304378196.png) (http://www.speedtest.net)
We've noticed some unusual behaviour with our LNS (login) servers recently so we're going to load the latest software versions on them and reboot one in the early hours of tomorow morning and then the others a few days apart.
Thanks Simon!
This work has been postponed 24 hours.
The new software purports to support IPv6 prefix delegation in a slightly different (better) way. It is backwards-compatible so won't affect any exisiting customer configurations but we want to test this some more in the lab before we roll it out.
Hopefully this will fix the problem tonight as its starting from 10am now and clears up around 11pm.
Sounds familiar to one of the other congestion problems a few years back. The software was not seeing some the load/customers for some reason, and thus was not load transferring. Left a few stuck on the congested server, and while other was idle. That only affected ASDL2+ customers AFAIR. :P
Dunno; but as the doubling of latency/25% loss of top speed/up to 5% packet loss for me is all exactly during IDNet's former "peak" hours, and unique (as far as I can tell) to IDNet's service; with normal "off-peak" service, I'm not sure it is wholly an addressing server issue? Their network must surely be suffering as people max out their new higher daytime allowances to get their money's worth? Anyhow the margins that FTTC gives above what I think any sensible user reasonably requires for a home connection, at least, means there is no practical problem, but perhaps their network doesn't quite live up to its claims. Not surprising really, but I emphasise, not a criticism; just how it is in the real world. Staying on an old package, and keeping most use off-peak, I'm OK!
Certainly I or should I say we have been streaming old repeats from Sky On Demand recently, something I would never have done before the tariffs changed. It's not for me about getting your money's worth however it's more about having the flexibility to use your connection as you wish to without feeling inhibited by the peak restrictions. I agree this must place an additional strain on IDNet's network but in terms of throughput for myself I'm not seeing an issue in terms of the usability of the service because as you say the margins with FTTC are above and beyond what I need for streaming HD TV.
It's not about speed drops etc, the main issue of this post is the increase in packet loss & max latency.. which on any connection causes issues with gaming, skype calls & ssh connections.
My connection dropped around 5am ish this morning, I take it that was the software update / reboot happening? After that I had packet loss & a higher min latency.
Just before 10am my min latency dropped down to 10ms.
My connection which has been sound while others have been complaining has gone bad this morning, was the software updated overnight?

I spoke with support yesterday, Brian couldn't see anything wrong with my line.
Just looked at my line and as others have noticed something happened around 8:45am when there was a bump in minimum latency:
(http://www.thinkbroadband.com/ping/share-thumb/da2e6e0d7ee7f17001b496c7ecb9f949-15-11-2012.png)
Other than that as has been said, come 10am everything goes a bit meh. Still not impacting my use but as on previous occasions I'm struck by the apparent disinterest from IDNet. I know these aren't official forums but the onetwo official responses we have had didn't really demonstrate a keen interest in the phenomena and a desire to get to the bottom of it.
From their web site:
"By refusing to oversubscribe our broadband services, we always ensure that bandwidth investment exceeds customer demand -guaranteeing you the highest possible performance and reliability from your connection."
"Our network ¡s one of the fastest, best connected networks in the UK, with points of presence in London and Amsterdam. At these exchanges we have peering agreements with over 500 networks which enable us to pass traffic at up to Gigabit speeds, delivering the highest performance and lowest latency that is technically possible."
:-\
Looking at Andrue, Glenns and my graphs something definitely happened around 8.45am this morning. Since then the maximum latency yellow plot is trying to replicate Bart Simpsons hair style :dunno:
Please reboot your router to force a conection to another LNS whilst we sort out this issue.
It seems mine reconnected to a good LNS when something happened at 10am ;D

Certainly mine has changed back to 'normal' this evening after a forced disconnect. Looks exactly the same as Paul's TBBQM before and after.
Thanks, Simon - it's nice to know someone is looking into it.
Mine has lost the spiky latency peaks and packet loss but the minimum latency is still higher than normal.
Mind you Speedtest.net appears to have got a bit confused:

Been a while since it did that, I'd almost got used to trusting it.

It seems to have started about when the idnet.com mail servers became accessible again, no obvious connection with the red spike (PPP drop I think) at ~5am.
I agree Bill the mail servers were unresponsive this morning first thing, I kept quiet since no one else was posting. You may of course have switched LNS server in the early hours when you dropped PPPOE which may explain why your seeing what the others in this thread have being seeing.
Quote from: Steve on Nov 15, 2012, 21:06:43You may of course have switched LNS server in the early hours when you dropped PPPOE
I think you're probably right- I hadn't noticed before, but there's a barely visible decrease in ping time after that spike... maybe if he looks up the relevant LNS servers, it might give Simon (IDNet) an extra clue?
happily, nearly enough customers have now left the dodgy server for things to have almost returned to normal for those of us who didn't! :fingers:
I've been noticing a slight increase in maximum latency and packet loss over the last 2 days again.
All be it small, but it's how it happened last time.. Anyone else?
Again, seems to start from around 10am and get worse before correcting itself.
I've had a look at the staff's and I'm not convinced I'm seeing anything like what we saw before, there's the odd pixel of red however.

It's how mine started before I made the topic. I will keep an eye on it though.
Paul, that's exactly what I'm seeing.
I'm not sure it's solved properly yet. I had cause to do some downloading recently for a change and noticed that my single threaded downloads never go above 3.5MB/s - from anywhere. In discussions elsewhere it was suggested I try a download accelerator and lo and behold - I can get 7.2MB/s again using one of those.
Now sure some sites throttle but two of the sites affected are the Ubuntu download site - usually given as a good test example - and more significantly the TBB test files (http://www.thinkbroadband.com/download.html). Clearly TBB is unlikely to be throttling those ;) The TBB tester is also apparently capped all of a sudden and the mods have confirmed that their tester is single threaded. Meanwhile speedtest.net is unaffected and it uses multi-threading.
I've sent an email to support and also pointed out that it started on the 15th which is when I rebooted and lost the congestion spikes.
If the download accelerator can supply the throughput does that not suggest that the 'bottleneck' is not between you and IDNet?
Quote from: Steve on Nov 27, 2012, 21:28:21

Not quite as I understand it. It just suggests that something (and it could be almost anything) is imposing the cap. Some possible causes could be:
My router.
My cabinet (I think).
BT Wholesale.
IDNet's servers.
Basically anything that is monitoring and 'directing' TCP/IP traffic is capable of throttling on a per-connection basis.
Given that it impacts all the servers I try - one of which is very unlikely to have such throttling - it seems it must be something fairly close to me so one of the above. It seems more than a coincidence to me that this seems to have started after the recent congestion work. My connection's latency as reported by TBBQM has never recovered and nor has my upload. You can see the change here:
(http://s9.postimage.org/dcnsvhrv3/satats.png)
I'm not suggesting deliberate throttling but I do think this suggests a configuration error with IDNet's network.
OK , so if I understand it correctly your suggesting that somewhere there is a throttle on single threaded downloads. Hopefully support will shed some light.

It sure seems that way to me.
It all seems like being That Night Of The Year(
TM).
Not only have I been investigating network problems but that showed that my email server still wasn't happy talking to IDNet's. So I decided to apply an upgrade. Avast! decided it looked dodgy so the install failed half way through :eek4:
Thankfully after swearing at Avast and telling it where to stick its behaviour analysis the second install went through successfully and all is working well. But as is typical for That Night Of The Year(
TM) I'm about to try and go to bed while being hyped up from computer problems.
:rant2:
Lol (or not). Got my first response from Support. "Could I please run the BT speed tester". Sigh. I will when I get home but I can see how this is going to go.
If it's single threaded it'll report 28Mb/s with an acceptable range of 0 to 76 and Support will shrug and tell me there's nothing they can do.
If it's multi threaded it'll report 76Mb/s and Support will say everything looks good.
I really do want to 'like' IDNet but it's not easy. I sent quite a lengthy email last night including a link to this thread and all I got back was one paragraph asking me to run the BT speed tester. Looks a classic 'one-click boilerplate' response. It doesn't bode well :shake:
Well the good news is that Simon has responded so hopefully I've gone beyond stage one. He's suggested I connect direct to the BTor modem to eliminate my router which is a good idea. I can't really see it being the router since I haven't done anything with it but it's one less link in the chain.
Hope you find the reason for it. Remember to check on a second PC/Vanilla PC to confirm it's not software (Sorry if you've already done this :P ).
Also, normally I'd guess it's a limit on outgoing servers. FTTC/H is outstripping demand for download, is outstripping the services ability to upload/deliver. :D
But in your case I'd guess there is something else at play.
PS, routers can have quality of service settings. Also they can have "bugs" or slow data processors. I wonder if the Fiber connection is too quick for your router to handle? But we will see once you've eliminated the closes possible causes. :P
The plot thickens!
I plugged my laptop directly into the BTor modem and the problem was still there. I ran the BT speedtester and got:
Download speedachieved during the test was - 67.93 Mbps
For your connection, the acceptable range of speeds is 12 Mbps-0 Mbps.
IP Profile for your line is - 77.43 Mbps
So either the BT test is multi-threaded or else..I dunno. But ISTM that puts the ball firmly in IDNet's court. BT say I can hit nigh-on 70Mb/s. I can indeed hit that with multi-threading but on single threading I'm stuck at about 28Mb/s.
Would someone else care to try one of these files:
http://www.thinkbroadband.com/download.html
Not that I think there's going to be any TBB side throttling in play. It'd be pretty damn' stupid to throttle the speed of files that exist purely to test your download speed :D
We're not capping any services. I recommended that you try a different computer and OS. But if you're getting better throughput with multi threading enabled then I'd recommend that you leave that setting turned on.
@andrue I think it's something local to you..
I can easily do a single thread download at around 7 MB/s which is around 60 Mb/s & my profile at the mo is just slightly higher than 60 Mb/s
I think it's difficult to quantify why on a download one is unable to achieve maximum throughput, I had a quick check last night and concluded that I've no idea why some sites/servers do not give my line maximum throughput. A BT Speedtest was giving 40mbps (5Mb/s) so was Speedtest.net I agree they are only relatively small files but does this not prove my connection is capable of the speeds displayed. However file downloads from Apple and TBB test files were limited to around 2Mb/but that's not unusual for my line downloading from Apple. It seemed on this occasion I was limited by the server's ability to give rather than my ability to receive.
Yep on an IDNet FTTC connection (though a connection on the old 40/10 profiles) I use a automatic regular speed tester which uses the TBB files, and over 15 months there has never been any difference between single and multi-thread testing, also using another download server (as it offers that option). Apart from the slight erraticism a couple of weeks ago the TBBQM has been utterly consistent too - no changes to latency, packet loss nor irregular latency spikes other than those accounted for by the use of my connection. It is useful though having a modem which provides (limited) stats - the connection is suffering a significant increase in all reported errors across the board recently (I suspect due to adverse weather, damp then cold on an old underground local loop line) - but it's not triggered any resyncs, INP change (which might show a higher level of interleaving being applied, perhaps?) or noticeable changes to the bit loading, although there is a bit more fluctuation in the range of reported speeds (+/- 20% rather than +/-10%). (Just seen other posts - downloads of Apple software are as quick as anything else though a Windows OS/IDNet DNS; though ITunes does seem to run at 50% of max throughput otherwise reported (and which is achieved on BBC iplayer/SkyPlayer) - I'd always assumed I was using it at busy times).
Is there any evidence that the higher 80/20 profile is less stable?
I have a simiar situation Steve but on ADSL2+ I sync at 15447 now downloading from Sky on demand is quick, but Apple is always slow. I use a different DNS to idnets like you do, (I use Symantecs DNS servers) maybe the Akamai system comes into play here and we are not getting the nearest servers from some sites (even though both Open DNS and Symantec both have servers in London) although whether they use them all the time is another issue as they balance the servers usage There is an Article saying that fast DNS resolution comes at the cost of slower download speed, especially from Apples servers. http://lifehacker.com/5721188/fix-itunes-and-other-slowdowns-by-ditching-third+party-dns-servers
Certainly the DNS choice seems very relevant as what we think is a local download could well be intercontinental . Simon@idnet has clearly stated their position so any slowdowns must be due to other factors.
Yeah it's odd, I'll grant. Also I'm not suggesting deliberate throttling by IDNet.
However I didn't use to have this problem. I mostly gave up on the TBB tester a while back but that's because of a known issue with upstream throughput. I don't download much so I don't know when this actually started. The last thing I remember downloading at full speed was the last Win8 RC DVD.
I can say that it affects all three of my computers: An Acer laptop, a Fit-PC2 server and an HP desktop. They do all run Windows 7 but neither the laptop nor Fit-PC2 have Windows Update enabled so are essentially unchanged from months if not years ago. The HP machine is employer provided and Gawd alone knows what configuration that ends up with since it's controlled by corporate IT. Connecting the laptop direct to the BTor modem didn't change anything.
The other oddity is my upload on Speedtest.net. Simon didn't think there was anything significant there but that's surely an obvious difference that we know happened on the 15th as a result of this thread. What do other people get from speedtest.net? The BT tester said I could get 16Mb/s so how come I only get 12Mb/s all of a sudden ???
Anyway to re-iterate I'm not trying imply anything underhand by IDNet but I would very much like to get to the bottom of this.
I was going to ask about leaving the router out of the equation, but you've done that! (I recall I found that the Netgear wnr100 I (I think) - supplied by IDNet could halve my upload and download speeds (during downloads the TBBmeter graph was up and down like a yo yo compared to the "block" graph shown using my current router/modem). I also gather that some people have had faulty faceplates installed by OR (though as you're recent, I think, they should have sorted this) - can I believe be checked by using the master socket which still lies behind the frontplate if you're that interested? I know it's convenient to link it to the recent erraticism (which didn't affect my test result on speeedtest.net when it was happening); but things don't necessarily have the same cause just because of timing, I've found.
PS I may be wrong (usually am) but I think the "faulty faceplates" issue may sometimes not affect results on the BT speedtester and may be even speedtest.net which show peak speeds, but affect "real world" performance?

Oh too true. Computers can be pernickety beasts and one fix doesn't necessarily address all instances. I do have a wnr1000 but mines a v3. Also the latest firmware since the night before last (post dating this problem BTW). If it was a problem with 'horsepower' I'd think it would be there all the time but last night in some tests my download accelerator was hitting over 8MB/s with some Microsoft stuff. I think at one point it had 4 threads running at 2.1MB/s. Whatever the problem is it's not with the physical FTTC side.
Something be it my computer, my router, IDNet's routers, BT's routers or Uncle Tom Cobbly(**) just doesn't like single threads going faster than ~3MB/s.
So it's possible to deliver 'bits' to my laptop(*) at over 8MB/s it's just how you do it that has issues. I've just found this which sounds interesting:
http://broadband.mpi-sws.org/transparency/bttest.php
Again I'd like to distance myself from the overall tone of the article but it'll be interesting to see what it says.
(*)For the record before someone queries it my laptop is wired. I gave up on wifi shortly after getting FTTC. Around me there's just too many other people hogging the airwaves(** again probably :) ).

Well - how interesting. Glasnost said there was nothing wrong although it could only run at about 20Mb/s. However the problem has improved. Well..mostly. The TBB tester is still only saying 38Mb/s but the test files are coming down at over 5MB/s. It's not what it has been but the mysterious 3MB/s barrier seems to have been broken. And for the record I haven't done anything. Just got home and fired up my laptop. Meanwhile the same file multi-threaded screams down at 8.5MB/s.
I think that eliminates any equipment I own but beyond that I don't know.

Thanks to input from Andrue we have identified a possible issue with one of the LNS servers so we're going to reload it at 04:30 tomorrow morning. Consequently those customers currently connected will see a brief PPP drop as your connection is shifted to one of the other LNS servers.
Wow. And here I was thinking we might be turning into crazy people watching the fire/sky/clouds/sea/tv white noise looking for signals. :laugh:
It's really annoying when you find a problem, but the information to solve it is hidden in a "black box", through no fault of our own or IDNet's. It requires a lot of tinkering to figure out and use deduction to "see" what is on the inside.
Single threaded downloads being treated differently to multithreaded ones is a strange problem to have, but I understand it would be annoying if you rely on downloads for business (or even just netflix :D ).
Well the irony is that I don't download much and an accelerator was an acceptable workaround in that respect. What was annoying me most was not knowing what the problem was. Anyway my thanks to Simon and his team for pursuing it and putting up with me. As a programmer of many years I know that some problems take a lot of finding and sometimes the answer is where you least expect it.
Let's hope that's the answer :fingers:
You never know if it will effect others, or progress to another problem. Just imagine trying to find the reason in 2 years time, when everyone has FTTC and suddenly downloads are capped to 3meg. :laugh:
Much better to find it now when it's quiet and not "mission critical" on the time and wages. :thumb:
With IDNet it's not that they are perfect, as no one is. It's that they work really hard at trying to be perfect. ;)
Just checked with an Apple and a Ubuntu download I seem to be just over 4MB/s on a 42mbps line,which I guess is about right.
Im a tad confused, I thought the LNS servers were having new software after a 24 hour delay due to a testing phase, so has that happened and one has gone a bit awry, of did that never happen :dunno:

Ah, so that's what it was :D

Your minimum latency dropped a bit as well. Mine seems unchanged in that respect:

But I didn't go online from home before I left for work so I can't comment beyond that. I now have the joy of a day delving back into the depths of

Only about a millisecond... it still strikes me as highly ironic that I get very good latency but, not being a gamer, provided I don't have to measure it with a calendar I'm not that bothered about it. :evil:

It's ironic that the faster my connection the less I want to do with it. I think most months I rarely crack 8GB. Prolly downloaded more investigating this issue than in any week previously :D

I think that's normal - the way of the world is towards greater efficiency. It doesn't work for t'internet because the consumption growth is driven by playing around. I've always found it strange that the government treats it as a strategic national objective to watch films and play games, but that's democratic politics for you. :whistle: (I know I'll get criticised by those whose work is on the internet, but I'm not entirely sure about that 11th commandment that everything done by computer is better!)

Yeah. I can see me using it as an alternative to my existing satellite dish for TV eventually. But for now I have Freesat and Sky PVRs and that means I have almost total control of when I view things anyway. IPTV would only be better if it meant I could watch something as soon as the studio released it instead of waiting for it to be broadcast.
But I don't see that happening so for now even iPlayer and the like are just a backup for the rare occasion when my PVR lets me down.
Yay! That's better:

The upload is still wrong but that's a known issue with that tester.
Speedtest.net still seems to have low upstream speed though. But I think Simon has cracked the bigger problem.
See, thinkbroadband gives me the correct up but incorrect down all the time, thats why I never trust the speed test on that site..

That's unusual but I've seen one other report of that. Most of the error reports though are of the upload never being reported higher than 8Mb/s. For some their Flash tester is better although not for me.
It's irritating I've been using that tester for nigh-on a decade and until FTTC it was very accurate, very real world. In fact the recent problem here showed that. Speedtest.net kept saying my downstream was fine whereas TBB said it was crippled. Now granted we know why the two tests differed but it's an example of how TBB usually tells you what you'll get 'out of the box' whereas speedtest.net tells you what you might get if you use the right tricks.
Hmmm. Thinking about it - are you sure don't have a problem? What speed do the test files come down at? You can always keep more than one download off and see if the combination is better.
Just sayin' ;)
Test downloads from many sites, including downloads from steam always come in around 6MB/s which is right for my profile..
TBB speedtest was never good for me even on ADSL2, always reported slower speeds.
3 other speed test sites are all around 59000 kbps
Just tried TBB again and its come back with

Interesting. My connection had a sudden drop in minimum latency this morning. It's back where it was before the 15th. Anyone else seeing that?
(http://www.thinkbroadband.com/ping/share-thumb/146bdc3e069825f33024140ade69383a-03-12-2012.png)
I had a very slight drop at 4am this morning.
Didn't get one at 4am but my connection has seem generally faster since the drop at around 9:30am sat, dunno if anyone else got a drop then?
I hadn't noticed my earlier graphs:

So actually it looks like a rise over the weekend then dropping back today. It's not actually as low as it was prior to the 15th - just back the way it was before the weekend. How odd ???
On FTTC connections interleaving is always active, as soon as you get a noisy line the ping will go up as it increases the interleaving.. nothing you can do about it at the mo.
The time of day looks like an interleave change. Any changes to interleave depth on mine occur between 5-6AM

Could this variable latency be a sign of a local loop line problem, a weak joint perhaps, affected by weather? After the initial doubling of latency when interleaving was switched on my line (after 1 month) latency has been completely stable for nearly 15 months, and over every reconnection. I've seen an experienced BT engineer state that the FTTC DLM does react to emerging line faults well before they are picked up by any remote line test used by ISPs, though how you convince the ISP of that I don't know. Watch this space, perhaps? Unlocking or using a modem which gives you stats might help in seeing what is happening with errors and the SNR - from my experience a major variation seems to be required to trigger an increase in interleaving/latency, and perhaps vice versa.
