Gee how about we dont Talk. Gtalk/Gmail dead.

My Google Talk does not work, neither from iGoogle, Talk Gadget, Gmail, Jabber Network, iChat, etc.
Can it be fixed or is it doomed to just simply never work. The problem is it doesnt show my contacts which are online, or any contacts for that matter and my friends see me as offline. And yes the Turn on chat function is on.
