Steam maintenance took longer than usual - it's back up
Steam's regular maintenance took longer than usual, according to Valve. Per a post on Steam's Facebook page: "The routine maintenance on Steam servers this morning, Tuesday Sept 25th, 2012 is taking longer than expected. We appreciate your patience." So, if you tried to log in to a game, or tried to change your profile picture and couldn't - now you know why. It seems all systems are up and running now.
