DESCRIPTION
We've just seen many TalkTalk connected lines disconnect.
Resolution:

Many of our TalkTalk ADSL and FTTC lines dropped at 10:08. Most lines reconnected by 10:11, and the remaining by around 10:18. Cause is yet undetermined, we're awaiting updates from TalkTalk. They did report a 'network flap' that affected a smaller number of lines at 9:52, but we're not sure if these two sets of blips are related.)

Further update: TalkTalk do say that that drops were due to link flaps on fibres between their datacentres.

DESCRIPTION
We're investigating problems on our network which will affecting connectivity for customers.
Resolution: Sorry for the delay posting details - this is one of those occasions where there are not a lot of details we can post. The problems mainly related to our authoritative DNS servers which therefore caused issues with almost all services.

DESCRIPTION
We're seeing a high number of broadband lines dropping and reconnecting, we're investigating
Resolution: Line drops were caused when staff bought up an interconnect between our two London datacentres. The configuration of this circuit was intended to be separate from the rest of our network but somehow it did carry some traffic and cause this outage for some customers. We continue to investigate the cause in more detail.

DESCRIPTION
We're investigating the loss of a number of TalkTalk connected lines. Updates to follow shortly.
Resolution: Summary and further work

Here is a brief summary of this incident and what we are planning to do to improve matters.

  1. 01:12 Whilst we were running on a single interconnect to TalkTalk due to a previous incident, TalkTalk carried out planned work on the working interconnect causing all TalkTalk lines to drop. (Unfortunately is wasn't made clear to us that this work was happening, otherwise we would have been more prepared and this incident wouldn't have happened)
  2. 01:52 We bought our 2nd interconnect back in to service and about 70% of lines reconnected
  3. 01:52 about 30% of lines still had problems staying connected
  4. 05:37 After lots of investigation which led to use removing some internal LACP links and another 17.5% of lines connected.
  5. 06:16 Further work our side restored about 10% of lines, leaving a further 2.5% offline
  6. 12:00 TalkTalk's Planned work overran and their work was reverted and completed.
  7. Early afternoon: The remaining 2.5% of lines reconnected eventually - these were most problematic and seemed to have either stuck or blocked sessions within the TalkTalk network - a problem probably a result of TalkTalk's planned work and was resolved by TalkTalk clearing sessions manually after their planned work.
We have scheduled the early hours of Thursday 17th September to investigate further one of our core network switches that has been the cause of some of these problems today and last week: https://aastatus.net/37312

We do apologise to those affected by this incident, especially those who didn't reconnect successfully early on.

DESCRIPTION
We're investigating line drops that started at around 4PM and is affecting various broadband lines.
Resolution: We'll be investigating the actual cause of this incident - there were a number of different and separate events that occurred at nearly the same time (just after 4PM on Sunday) and we'll be investigating them to see if they can explain this incident. We'll post an update to this post with further explanation as and when we have one.
