July 02 - Network Disruption Details

Resolved [02/07/2021 13:44]

Whilst investigating a degraded performance issue on a dark fibre at our LD8 PoP, a third party engineer inadvertently disconnected another dark fibre that connects LD8 to a third location. This subsequently resulted in LD8 becoming isolated from the rest of the network for a short period, between 00:06:02 and 00:09:56.

As previously reported, during this time leased line circuits terminating at LD8 would have experienced a loss of connectivity. Broadband circuits were impacted further due to a large number of subscriber sessions that were terminating at LD8 disconnecting.

Whilst the majority of the affected broadband subscribers regained a session at another PoP relatively quickly, others whose sessions were steered to a particular aggregation router on the network failed to start. Our engineers investigated and discovered that the router was experiencing a fault condition and took it out of service. At this point the vast majority of remaining subscribers re-gained their sessions.

Apologies for the disruption this may have caused.

June 13 - Telehouse West POP Issue Details

Resolved [14/06/2021 10:00]

At 12:32:23 on 13/06/21 a supervisor in a core switch at our THW PoP experienced an inexplicable reboot. Shortly afterwards at 12:32:40 a hot standby supervisor took over the active role and restored the overall connectivity to the PoP.

The original active supervisor that rebooted was back in service as a hot standby by 12:41:52. By 12:54:47 it had brought all its line cards online following a full and successful diagnostics run. All connectivity was restored to the site by this point.

Non-resilient leased line circuits that terminate on NNIs directly connected to the rebooted supervisor would have experienced an outage between 12:32:23 and 12:54:47.

All other non-resilient leased line circuits as well as any broadband circuits that were terminating at THW would have seen a loss of connectivity between 12:32:23 and 12:32:40.

We have raised this to the vendor's TAC for further investigation. The device is currently stable and not showing any signs of issues. As such we do not deem the site to be at further risk at this time.

Apologies for the disruption this may have caused.

May 18 - TalkTalk DSL Circuit Outages Details

Resolved [18/05/2021 17:01]

October 14 - Unexpected Broadband Session Drops Details

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.

September 26 - Virgin NNI Outage [30 circuits Affected] Details

Resolved [26/09/2020 08:18]

Fault was tracked down to a power failure within a Virgin Media rack. All circuits are operational.

September 15 - Broadband network outage affecting TTB based circuits Details

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.

August 31 - TalkTalk Ethernet Outage [LD8] Details

Resolved [31/08/2020 22:47]

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.

August 30 - Problems with Internet Routing / CenturyLink Details

Resolved [30/08/2020 21:25]

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.
