The London LD8 datacentre suffered a loss of power at 4:30AM. Our status page was affected and this is a new post which will have some updates as services are being restored.
This post is lacking lots of detail of the problems that we've had today as our status page, although hosted in Amsterdam on someone else's network, routing to it was also affected.
Power has just been restored, and this will be causing some connectivity problems for a short while whilst the network settles down and we update our configuration of various routers.
We are in the process of rebalancing lines - this involved moving lines back to the LNSs that have been down all day. This means some lines will have a short (minute or two) drop whilst they reconnect.
Service is mostly back to normal now.
