If you were hoping to get a little Team Fortress 2
or Left 4 Dead
in tomorrow night you might be SOL as Valve is taking Steam down
to apply a few software patches tomorrow night from 6-9 PST. You also won't be able to download any new games or yell at fellow subscribers in the forum as well so if you were looking to pull down all that hot new Lucasart content you better do so before they take the servers offline.
