I can’t play my Steam games. Why?
Apparently a storm has caused power cuts in Seattle. What!? VALVe only have Authorisation servers in one place? Are they completely mad!? It wouldn’t be so bad if the offline mode actually worked but despite me setting steam to log me in automatically and remember my details it has deleted them so I can’t log on until they get the servers back. From my research as to why this happens it seems that if you are connected to a network but can’t get to the Steam servers it assumes you are a pirate and deletes your local data (not game content fortunately), in order for offline mode to work you have to disconnect from any network (even a LAN which isn’t on the internet) before you start Steam, but once it has deleted your offline data on your first attempt to connect, it is too late.
Lets hope VALVe fix this in a future update, I’m not going to hold my breath though.
EDIT: The servers are back up now. As far as I can tell from the stats page it was down for just over an hour. Still it makes you wonder what would happen to your games if they had a more serious problem…
EDIT 2: I took a screenshot of the stats page for later reference:
