We have just been notified by RapidSwitch, whose datacenter Fr3d uses to host the UK server, that it is likely that there will be a loss of connectivity on their network this evening at around 23:00 UK time.
This is due to RapidSwitch having to perform emergency network maintenance:
The maintenance is to perform an emergency upgrade of Cisco software. [...] The Cisco TAC team have diagnosed a fault with the software on the router in the form of a memory leak. Cisco has supplied us with a new version of the software for the router which will fix the memory leak and slow performance.

They say that this maintenance should take no longer than 45 minutes, and that they will do all they can to speed everything up and reduce the maintenance time.
To maintain network cohesion (as much as possible), the DE server will automatically failover its link to the US server in the event it loses its connection, and cannot reconnect, to the UK server.
Update @ 01:50 25/09: RapidSwitch seem to be back online now. No word from them yet as to why the maintenance took so long; we will update this post when we know more.
