We are now receiving responses from the various affected systems. Confirmation of a resolution hasn't been announced by Openreach, so services should be considered at risk.

Resolved [14/10/2020 11:15]
Apologies for the session drops this morning. The cause was linked to additional interconnects being patched into one of our London POPs. This caused an issue with one of our broadband LNS which dropped sessions, only for them to be able to reconnect. It would have impacted any circuits routed via that LNS across TalkTalk and BT Wholesale.
This was unexpected behaviour and should not have occurred. We will continue to monitor and will raise this with the manufacturer as a suspected bug.

Fault was tracked down to a power failure within a Virgin Media rack. All circuits are operational.
Resolved [15/09/2020 16:20]
We have seen near-normal levels of sessions restore through the afternoon. Anyone unable to reconnect should be able to do so with a power cycle. If this doesn't address it try powering down for an hour and reconnect. Failure to connect still may require assistance from our support team.
We will not terminate sessions to force a reconnection back to Telehouse North, they will naturally spread out as sessions drop of their own accord.
We are reviewing this outage internally, but ultimately the cause lay with the carrier.

The root cause was TalkTalk maintained hardware failure affecting 1 Ethernet NNI of ours and 6000 other B2B clients. TalkTalk fault incident resolution states:
<-- snip -->
NOC monitoring identified an FPC10 (Flexible PIC Concentrator) failure at NGE001.LOH. This caused a total loss of service to approx. 6k B2B circuits from approx. 12:47 (31/08). The Core Network Ops team were engaged and their investigations found that the FPC10 had failed and could not be restored remotely. To restore service as of approx. 17:23 a field engineer attended site and replaced the faulty FTP10 with support from the core network ops team. This incident will now be closed with any further root cause analysis being completed via the problem management process.
<-- snip -->
Apologies for the disruption caused this afternoon.

The issue was resolved around 16:10. CenturyLink responded via Twitter to say:
<-- snip -->
We are able to confirm that all services impacted by today’s IP outage have been restored. We understand how important these services are to our customers, and we sincerely apologize for the impact this outage caused.
<-- snip -->
Although we and their other global customers withdrew routes and shut down peering sessions, they continued to announce them to their peers regardless. This caused black holing of any inbound traffic routed via CenturyLink. All affected customers were left powerless and it has been a case of having to wait for them resolve the issue.
Thankfully less than 10% of our overall traffic routes in via CenturyLink's network, so the impact was minimal. We know of only a small handful of destinations that were unreachable during their outage. Apologies if your access was disrupted.

The issue was related to LINX (the London Internet Exchange), which has now been resolved and would have potentially affected several Internet providers in the UK. We are awaiting a full RFO from them to confirm the cause.

The cause has been located and service has now stablised. If a connection hasn't returned please power cycle the router to force a reconnection attempt. Apologies for the disruption witnessed.

The upgrade was successful and cleared the fault condition as suspected. We have been monitoring for the past hour and have not seen any further instability.

Virgin have supplied the following reason for outage:
"In relation to the issue identified in the London area regarding loss of service. This issue was fully restored at 20:43 yesterday evening when a faulty DC output breaker was discovered at our Hayes hubsite and services were moved away from it onto a different output breaker. All services have been stable since that time."

This issue appears to be resolved now, although we are monitoring the situation carefully.
Reason For Outage - TalkTalk identified an issue with a third party peering provider, Iomart, who incorrectly advertised a subnet. This was a highly unusual event, and hopefully one we never see repeated.
