Hello,

Since yesterday I'm having issues resolving forum.xbmc.org http://www.xbmc.org etc.
This is from my broadband provider Tiscali(Talktalk) in the uk.

I run other networks as my job and they are fine.

I just wondered if something changed recently?

Reverse lookup of 205.251.128.242 resolves fine to xbmc.org but trying to resolve xbmc.org fails direct to their dns servers.

If someone could let me know if there are any recent changes before I start yelling at them to get it sorted.

Don't worry is my awful ISP's DNS system.

They cover a large amount of the UK though so other users may be experiencing problems.

For some reason there dns won't respond to a couple of names xbmc's being one of them.

Dumped them in favour of google dns. I am not going to look back.

Have you told your ISP about the issue? Please yell at them on our behalf

Yea, unfortunately seems there's not much we can do.

If you can't reach http://205.251.128.242 , please let us know. Otherwise, my only suggestion is to use something like opendns and yell at your isp.

edit: Btw, no recent changes on our end.

Yea I jumped through their 50 hoops to get forum posting access last night.
There websites so bad they forced users to enter security questions in caps rather than doing noncase senstive comparisons on the backend....

It's here if you want to follow it:

Sadely when using a faulty dns the webpage does not render very well / if at all when accessing by ip.
Their dns server does not return unknown just times out which lead me to believe at first it was a site error.

I had the same problem with UKOnline (Easynet) and I did some tests that proved that their DNS servers had no entry for xbmc.org, despite it being there 2 days earlier. Their recommendation was to use Google's public DNS instead of theirs, but it would be worth asking why so many ISP's DNS dropped xbmc.org at the same time.

Problems here with Virgin broadband. I have to F5 a few times to get it going again

Exactly. Seems suspicious. Also problems here in Denmark, with TDC (the largest ISP in Denmark). Problem started about 2 weeks ago. Somtimes their DNS can resovle xbmc.org but a few moment later, it's gone for hours again.
Maybe if xbmc.org's authoritative NS' gives bogus reply's sometimes, maybe it's cached by negative TTL? Just a guess...

@ theuni

I noticed you asked for some dig outputs on another post regarding this....

On talktalk's dns (ID mismatch ??! Perhaps here lies the problem):

Some problems with Sky Broadband (EasyNet) UK Too.

Seems to be alright now. Though DNS resolving still seems a bit on the slow side. Using Google DNS and its fine now.
