Steam is down?

Nope,restart Steam.

Never.

Down for me

It's only you

Works for me :D

can't connect to server. ;-/

The website works fine, but it doesn't let me connect to play D:

No, just restart your steam then it should be fixed

Now it works :D

It happened to me like an hour ago. In the site appeared the message "Error: The community is offline" or something like that, and the client always started in Offline Mode, even though I selected "Go Online" and was forced to restart the client, it always restarted in Offline Mode... The way I fix was to close the client as always through "Exit", waited a minute and launched it again. Very strange... :P
