We have now received a further update on this.

Equinix's overview of the Incident:

At 04:33 on the 18th August 2020 at our LD8 IBX, Equinix facilities technicians responded to a fire alarm. Once deemed safe to do so, the site team started investigations into the source of the alarm, it was noted that it had originated from the building 8/9 main power room. The building fire suppression system was not activated nor required to do so at any point.

Site technicians proceeded to the main power room to investigate the issue and discovered smoke (no fire) within the room. The cause of the smoke was identified as a result of a failure on the main static transfer switch common output cabinet of the Galaxy UPS system. The fault had caused the system to shut down, resulting in a total loss of all customer power supplies supported by busbar risers ISP8 and ISP9 both of which are connected to the same UPS output.

Following the power beginning to be restored yesterday at LD8 many providers and transit operators have been working to restore their services which has affected the internet transit at large. Please note we have not received a 'works complete notification from Equinix at this time'

We have been kept informed that some of the larger operators such as LINX (London Internet Exchange) had to replace their line cards but that work is now complete and for many recipients of service there appears to be now a stability since many providers have completed the works overnight. 

Due to the large and unexpected impact of a power outage affecting so many providers to the internet we are continuing to monitor this situation as their may still be works ongoing with some providers that has not been flagged and also residual after effects to service provided generally.

Following Equinix resolving the issue with the outage, providers within the datacentre have equipment which is starting to come up and internet routes are starting to be seen again.

It has been reported that some systems at LD8 are restored, although the power issue is ongoing.

However many internet routes which are located at Equinix LD8 are still down.

Engineers are outside of Equinix LD8 waiting for when they are allowed to go in as there has been an ongoing fire alarm.
