Steam Servers

Are the steam servers down because every time I try to join a game it says "this account doesn't own this game please sign on.."blabla

They were down earlier, but it has been up hours ago for me.

Last i heard there was a power-cut, I dont know if there back up though.

Ive had that happen to me before, i just restarted my steam and it worked normally

I just got steam, and its running quite slow,

anyone know how to unblock msn messenger with nortom antivirus. i mite just uninstall it,
