We are aware of a routing issue which is affecting some servers in London. The routing issue is causing websites to time out, and is being worked on. Seven servers are affected:
Cake
Prime
Wordsworth
Hegeley
Antbear
Africannights
Ratchet
Update 14:30 the Datacentre is still working on the routing issue
Update 14:55 Everything appears to be running normally again. If you do have any issues, please submit a support ticket.
