If it was your first time connecting to a Spawnpoint server, or you were banned almost instantly when you got into the server, SteamBans may have nabbed you. If thats the case you will not be able to join any Spawnpoint/PHXX servers, or the 13,000+ servers in the SB area.
Though that seems less likely, if that is the case, Welcome, go away!
