At around 1:51 today TT dropped offline. We are investigating.
We've seen reports of other ISPs lines via TT also having the same problem.
This looks very much like a major outage within TalkTalk. Our BGP session to them that carry our traffic is down at one datacentre and up and our second datacentre but with no prefixes being advertised to us from TalkTalks side.
We are seeing some lines starting to reconnect.
We are seeing some lines starting to reconnect.
No word from TT as to the cause of this, but we'll update this post in due course.
Majority of lines are back on now - waiting for the last ones to reconnect.
It looks like this was caused by some TT planned work of which we were unaware, and clearly did not go to plan. We are trying to get a full explanation from TT. In the mean time the problem is resolved. If you are off line, try restarting your router to force it to reconnect.
