im also having thses problems... and have had them for along time, ive always been able to get on a few servers some nights none not even the regular ones. i have also tryed most of what you have and just lost connection to a server and i cant join any now.. thats how i found your post. anyway i read somewhere it might be ISP related in the way in handles/loads the server browser and the ISP might be blocking connections as it mimics P2P file sharing. im on Virgin Media btw.

have you tryed "C130J_US_EP1" which is the OA C130.
