From Steam

Planned Downtime on Monday October 11th

Beginning at 4:00 am Pacific time Monday October 11th, we will be performing software maintenance on the Steam servers. We expect the resulting downtime to last four hours, putting the end of the window around 8:00 am Pacific time.

Some Steam services will be offline during this time. Affected services will include the Steam Community, in-game matchmaking or lobbies, downloading games from Steam content servers, and making purchases from the Steam store. Games that do not rely on Steam matchmaking services should remain playable.

We will work to make this downtime as short as possible. Thank you for your patience!
