We're on our way to move HG to a new set of servers today. HG may not be available from today 7am EDT (1400 GMT) 'till around noon. We'll also be offline this holiday weekend (September 1 - September 4) in the US as we finalize the move and make sure everything is working.
Status updates, when available, are posted to
