Steam Down For Maintenance This Thursday

Valve let us know today that Steam, its online multiplayer hub and shopfront for the PC, will be down for maintenance this Thursday, February 4.

It's scheduled to come down at 1800 PST, Valve estimating it should take around three hours to perform the necessary fixes. During that time most of the network will be inaccessible to users, so don't plan on using the Steam community, buying games, playing multiplayer titles or downloading stuff (like updates, etc).
