The machine which handles the main assignment server (AS) and the stats update is currently down. We expect that this machine will be back up by 10am pacific time. Since this has happened previously somewhat recently, we are looking into transferring some duties on this machine to both keep it less loaded and to lessen the severity if it goes down again.
This means that the stats update will be down until we get the machine back up, but the back up AS should handle all classic clients, and the PS3 and GPU clients are unaffected (as their AS is on a different machine).
