... because Valve are doing maintenance from 12PM (GMT+10 aka AEST) onwards for up to three hours.
Steam News
Beginning at 6:00 pm Pacific time Thursday August 6th, we will be performing software maintenance on some Steam servers. We expect the resulting downtime to last three hours at most, putting the end of the window at 9:00 pm 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.
News updates and any further information will be posted in this space.
We will work to make this downtime as short as possible. Thank you for your patience!
EDIT: Friday, not Saturday!
