I woke up to a down server and a number of messages on my phone from friends that help out with keeping me informed when I'm away from my PC. I couldn't even get in via the text based SSH interface, so Support were called, and they're working on it. I'm a bit late posting this as I was busily sanding away at the intakes of the L-29 Delfin I'm building during the down-time. Sorry 'bout that! :$
EDIT: As of 15:41 we're back :) A reboot was done after some investigation, so the forum is back and running.
EDIT: 11:29 21st Feb 2014 and it's off again. We got a quick response from support and they're looking into it. Sorry for the interruption folks, but we'll resume normal service as soon as we're able :)
EDIT: 12:50 and some database errors that weren't immediately evident have cropped up now we're using it again, so I've set a repair process in motion. The server will be unresponsive or slow until this has finished, so bear with us.
