MAJOR Closed Line Drops
AFFECTED
Line Drops
STARTED
Dec 15, 01:00 AM (9½ months ago)
CLOSED
Dec 15, 01:58 AM (9½ months ago)
DESCRIPTION
We're investigating dropping connections and routing problems that started at 1AM (15th December)
Resolution: Many of our routers lost their BGP connection to our internal 'route servers' - this caused some of our LNSs and edge routers to loose connectivity and their connection. This resulted in customers being unable to reach many places on the internet for a short while. Logs and other data have been captured and will be further investigated to find the cause.

Lines connected on the witless LNS dropped and are in process of reconnecting.
Resolution: The Witless LNSs suffered a crash which was caused by a bug in our CQM graphing code. This bug has been fixed and is in the process of being tested and we will then roll out the new software to the the Witless LNSs overnight as 'emergency' planned work.

Sep 28, 08:00 AM (1 year ago)
DESCRIPTION
Following on from the problems this morning, TalkTalk are performing some emergency work overnight, tonight. The work will start at 10PM and will carry on through to 6AM. They say that their work before midnight should not impact circuits, but the work after midnight may cause some reconnects.
Resolution: TalkTalk have emergency overnight work that failed and turned in to an outage causing circuits to drop. We took our Telehouse connection out of service and lines reconnected via our Equinix link and have been stable since 08:30. We'll leave the Telehouse link down for the moment in case TalkTalk schedule further work on it.

Jul 20, 07:29 AM (1 year ago)
DESCRIPTION
We're investigating a problem causing some lines to be reconnecting.
Resolution: A bug has been found in the LNS code which erroneously limited the number of connections that would successfully connect. This has been fixed. We will update the software on our test LNS (B.Doubtless) overnight. We'll then reschedule an upgrade of the production LNS (X.Witless) and bulk-move of customers for later in the week.

MAJOR Closed Internet
AFFECTED
Internet
STARTED

CLOSED
Jul 06, 03:08 PM (1 year ago)
DESCRIPTION
at around 14:45 there was some sort of problem that affected traffic, we're investigating the cause.
Resolution: We caused a network loop between two of our switches in one of our London datacentres. This was caused by loading wrong software variant on to one of our test FireBrick FB9000 routers; the software variant that was loaded didn't have the LACP feature and when the FireBrick booted it caused a network loop. This caused a broadcast storm and general chaos until the switch disabled the ports. We do apologise for the inconvenience this caused customers this afternoon, lesson learnt and software builds have been changed to include LACP in all variants.
