I don't know if it helps but the site loads perfectly here in Spain using Telefonica's DNS.

Ray,

Brian has asked if clearing the DNS cache helps, could you try for me please? Just need to run ipconfig /flushdns from a dos prompt.
Title: Re: Help please
Post by: Ray on Sep 16, 2011, 15:39:56
Still the same, Glenn, I've even cleared the Browser cache as well.

Thanks Ray.

Couple of more things Brian has ask to check;

QuoteCan they set the DNS in the TCP/IP settings of their PC?

Also are they able to ping the site?

Support are able to access the site from their office

I can try when I get home, but if someone could answer the above questions it would be appreciated.
Title: Re: Help please
Post by: Rik on Sep 16, 2011, 16:19:38
I can't reach it or ping it, Glenn, and I've got DNS set in the TCP/IP settings.
Title: Re: Help please
Post by: Glenn on Sep 16, 2011, 16:23:25
OK thanks, I'll let Brian & Simon know.
Title: Re: Help please
Post by: Rik on Sep 16, 2011, 17:22:04
Still not working here, Glenn, after another DNS flush.
Title: Re: Help please
Post by: Glenn on Sep 16, 2011, 17:32:54
Simon did take a look at first but all follow up mails have been from Brian, I think he has now gone home, so it may have to wait until Monday.
Title: Re: Help please
Post by: Rik on Sep 16, 2011, 17:34:06
He's been on earlies this week. Oddly, I would have expected it to be a job for Martin.
Title: Re: Help please
Post by: Glenn on Sep 16, 2011, 17:35:38
The strange thing is, inside their office network the site loads fine using the same nameservers.
Title: Re: Help please
Post by: Rik on Sep 16, 2011, 17:37:48
That's weird, but I've known problems with the forum running like treacle and it's fine for them. I wonder if they connect differently to the network than us - though that really shouldn't affect DNS, of course.
Title: Re: Help please
Post by: Glenn on Sep 17, 2011, 17:40:33
Simon has cleared the nameserver cache, but I still can't reach the site, even after flushing my DNS cache, anyone else reach it from an IDNet DNS?
Title: Re: Help please
Post by: Rik on Sep 17, 2011, 17:42:04
No. :(
Title: Re: Help please
Post by: Simon on Sep 17, 2011, 17:43:39
Nope.

Server not found using my iPhone via wifi on IDNet dns.
Title: Re: Help please
Post by: Niall on Sep 17, 2011, 18:59:41
Using 3G it loads fine (and fast).

Post by: Glenn on Sep 17, 2011, 19:05:05
Thanks for trying

Post by: Lance on Sep 17, 2011, 23:06:20
Could they be blocking Idnet ip addresses?
Title: Re: Help please
Post by: zappaDPJ on Sep 17, 2011, 23:29:12
That was my first thought Lance but it appears they can access it from IDNet towers :dunno:
Title: Re: Help please
Post by: Glenn on Sep 18, 2011, 08:44:19
Simon seems to think it's a problem at the other end, but that doesn't explain why the connection is fast to resolve from other DNS servers?

QuoteThe Authoritative nameserver for this domain is flaky - it only occasionally gives a valid response. This problem is magnified because the the time-to-live for the domain is set to 300 seconds (5 mins), where the norm is 48 hours.

The link I sent tests a bunch of DNS servers. Try it, then wait 6 minutes (for them to all time-out their caches (as instructed by the domain's time-to-live)) and then run it again in another window and compare.

Tried Idnet servers and was unable to reach the site but it is still ok on open dns servers. Maybe idnet servers don't like wars. :)

That wouldn't explain why Idnet users can access it using other DNS providers.
Title: Re: Help please
Post by: Lance on Sep 18, 2011, 14:02:59
True.

FWIW, I can get to it fine on my work laptop over VPN but can't get to it on my personal laptop over my idnet connection. Just tried both within seconds of each other.

Testing from 50 locations worldwide and their respective DNS servers have no issues resolving the address.

The site is now working, but seems to have a bad record somewhere as it drops out again periodically. If Brian refreshes the name servers, it works, but then disappears again after a while.

The IP address is 212.67.210.10, btw.

Thanks Rik, I reverted to OpenDNS to help with looking for my Grandfathers WW1 history.
Title: Re: Help please
Post by: Rik on Sep 19, 2011, 12:13:31
It's still resolving at this point, Glenn.  :fingers: It looks a useful site.
Title: Re: Help please
Post by: Simon_idnet on Sep 19, 2011, 14:28:32
It looks like they have fixed the DNS problem today as this site has been resolving fine for me all day so far.
Title: Re: Help please
Post by: Rik on Sep 19, 2011, 16:48:38
Thanks for that, Simon. Brian kicked the nameservers when I spoke to him and, since then, the site has been behaving perfectly. It's amazing what a good talking to from Brian can do. :)
Title: Re: Help please
Post by: Simon_idnet on Sep 20, 2011, 10:33:45
I also kicked our nameservers (resolvers) several times over the weekend.

The problem is that the domain has a very short TTL and their DNS server quite often refuses to answer [probably overloaded as all the domains on the server have silly TTL values] - our resolver then caches that bad record.

The error that is being returned by dig is SERVFAIL which means that the domain does exist and the root name servers have information on this domain, but that the authoritative name servers are not answering queries for this domain.

Thanks for the background, Simon. :)
