Title: Inaccessible Page
Post by: dlorde on May 22, 2010, 20:55:51
There is one web page that keeps giving me 'Page Not Available' errors when I browse to it:

http://confluence.jetbrains.net/display/IDEADEV/Maia+EAP (http://confluence.jetbrains.net/display/IDEADEV/Maia+EAP)

All the other web sites I use are fine, and this one used to be available not so long ago. Other people tell me they can access it, no problem.

Is it my setup or IDNET (i.e. can people here access it) ?

I can access it just fine

Works fine for me too. Have you cleared your history, flushed your DNS or tried a different brower. Also, are you using opendns or IDNet DNS?
Title: Re: Inaccessible Page
Post by: dlorde on May 22, 2010, 21:32:21
I'm using IDNET DNS. I've tried a different browser, I haven't flushed my history (I want to keep it), and I haven't flushed my DNS (how?).

Fine here as well.
Title: Re: Inaccessible Page
Post by: Bill on May 22, 2010, 21:47:28
I can't reach it (or ping it) on IDNet DNS.
Title: Re: Inaccessible Page
Post by: Bill on May 22, 2010, 21:53:06
Hmm, can't reach it with OpenDNS either :dunno:
Title: Re: Inaccessible Page
Post by: Lance on May 22, 2010, 21:59:22
It's odd. You've a IP address from a different block to dlorde so its not a simple IP address ban.
Title: Re: Inaccessible Page
Post by: dlorde on May 22, 2010, 22:00:51
Curiouser and curiouser... at least it's not just me. I just tried via my Windows Home Server and couldn't get to it from there. Although I can reach it OK from my PC at work (over VPN).
Title: Re: Inaccessible Page
Post by: Bill on May 22, 2010, 22:04:12
@Lance- what's the IP address of the site? If we can't reach it that way, something is very odd...
Title: Re: Inaccessible Page
Post by: Steve on May 22, 2010, 22:21:17
There something odd I can access the site but I can't get a DNS lookup
Title: Re: Inaccessible Page
Post by: Bill on May 22, 2010, 22:23:07
How about a ping, that should give it?
Title: Re: Inaccessible Page
Post by: Steve on May 22, 2010, 22:27:35
I can't ping it Mac network utility cannot resolve it either,same with traceroute but I can access the website via IDNet and OpenDNS how odd.Thats why I tried a DNS lookup elsewhere with no result.
Title: Re: Inaccessible Page

Weird... one for the network support guys I suspect. I'm definitely out of my depth!!!

Loaded fine for me and pings time out but managed to locate it as 184.73.234.255.

Post by: Bill on May 22, 2010, 23:15:04
Can't reach that either... strange or what?

1. On your local machine, open a command prompt.
2. Within the prompt, type ipconfig /flushdns

Thanks, but it made no difference.

The URL is of a safe site  - it's the download page of the latest beta release (Early Access Program) for the JetBrains IntelliJ IDEA Java development environment - (JetBrain's IntelliJ is the leading commercial Java development environment).

For some odd reason it has become inaccessible to some people.

Still not working here this morning.

Can't reach it on that IP either, but the address bar immediately shows http://confluence.jetbrains.net/ so RDNS working?

Weirder and weirder.

Especially as the analysis shows zero errors.  I can access the site from either IP (Russia or USA). The ping/tracert timing out is no issue as they have probably disallowed them to prevent DDOS issues. The Amazon AWS server is used for dns and is working correctly.

Why some people cannot access it is very odd.

Still a few replies coming in on tbb; seems to be the same for various ISPs, not just IDNet.
Title: Re: Inaccessible Page
Post by: dlorde on Jun 20, 2010, 11:52:01
Have there been any developments with this strange problem?

I've tried numerous DNS servers and can't access the site from here through IDNet, although I've had no problem from work (different ISP).

If it helps, the main site, www.jetbrains.net is accessible, but www.jetbrains.net/confluence redirects to http://confluence.jetbrains.net, and it seems to be this that is inaccessible.

Should I raise it as a support issue?
Title: Re: Inaccessible Page
Post by: Rik on Jun 20, 2010, 11:54:17
Well, all three work for me, so I'd wonder about local issues, eg firewall.
Title: Re: Inaccessible Page
Post by: DorsetBoy on Jun 20, 2010, 12:07:05
Which browser are you using?

www.jetbrains.net/confluence redirects to http://confluence.jetbrains.net

1) They are using an http address, not a www. and 2) the redirect is to a sub domain ,so they have probably moved the pages to a new folder.

Your browser settings or firewall may be preventing access to http addresses.

Hey thanks Rik - that worked a treat!   8-)

Oh well, I only need it occasionally, so going indirect is no great inconvenience.

Ask the site owners to unblock you, or at least tell you why they are blocking you.
