Always getting "Failed to connect to server"

It's because the servers are down, they probably have found a unexpected hitch (probably the UK servers) which is causing them to take longer, I'm sure you'd prefer them to take longer now to try to stop problems in the future.

They might do a special event such as a '0 deaths weekend' or a '200%/300% event' to try to keep the community happy, I'm sure once they are done they will post something.
