DESCRIPTION
We are retiring our use of the Twitter API. This means that tweets and DMs we send from our systems will no longer be sent - this includes Status Page updates and broadband up/down notifications. (Though the up/down notification DMs haven't been working for some time now.) We are looking into alternatives, such as Mastodon, and will announce that in due course.

DESCRIPTION
Over night we have seen restarts on the new LNS used for L2TP access causing people to have to reconnect. Customers have been routed to the older LNS for now, and the situation is stable.
Resolution: Engineers will be working on the issue on the new LNS, and we expect to move back in the week at some point. Diagnostics have given a good clue as to the cause of the problem.

CLOSED
Jan 30, 12:20 PM (7¼ days ago)
DESCRIPTION
A small number of BT lines dropped and reconnected at 12:15. This does seem specific to BT and we're asked them to investigate. The lines did reconnect a minute or so after.
Resolution: BT say this was due to a ' transmission incident' at FARADAY exchange, saying: "Loss of service to 47 x 100GigE, 4 x 40 GigE, 138 x 10GigE, 1 x 1 GigE and 1 x STM-64 circuits. {Total 6291 GigE}. Suspected fibre disturbance however, unable to confirm."

CLOSED
Jan 31, 03:05 PM (6 days ago)
DESCRIPTION
We're seeing a small number of L2TP customers drop and reconnect - this has been happening since 14:25 and seems to be those connection that are using Virgin as the underlying ISP. It seems as though there is packet loss affecting Virgin's network.
Resolution: Connections have stopped disconnecting. We had other reports of packetloss on Virgin connections unrelated to our services, so it seems there was some sort of problem at Virgin's side.

Resolution: This has been completed. L2TP circuits are now being terminated on a different router. Any problems please contact Support.

MINOR Closed TalkTalk

TalkTalk

CLOSED
Jan 09, 01:00 PM (28¼ days ago)
DESCRIPTION
Since 9AM today we are seeing latency and packet loss on a number of TalkTalk circuits. The common factor seems to be a particular route the traffic takes within TalkTalk's network - this indicates congestion caused by a broken fibre or a faulty device within TalkTalk.
Resolution: From TalkTalk: "Resolution Details: Due to an ongoing Transmission issue we are having within our core network we have lost multiple 100G and 10G links , causing our core network to run at reduced capacity. During this period, we noticed an interlink between our edge routers was congesting causing issues for customers. We have moved traffic away from this interlink to restore service to normal operations. Technical / Suspected Root Cause: Traffic congestion in edge network. Traffic moved away to alleviate congestion."
