It was related to a hacker attack actually. Nothing fancy, but some script kiddie managed to get access to a low level user account, and was pinging other servers. It didn't actually affect ASC, but the data center the server is located at had a fit when my system started flooding their network.
I can't guarantee they won't pull the plug again, I'm in the middle of tightening up security. I caught the guy right in the middle of accessing the system, he was kind of idiot, but I'm the bigger idiot for letting it happen.
Yeah I don't like the downtime either - this site alone gets used over 6000 times per day, so I know alot of people are missing out while it's down, sorry guys.
