Weird server problem

[Shadow]

Hey whats up its shadow, ok this is really weird, lately whenever i try to join it just keeps retrying and saying server is offline, but i go on gametiger and it says its up.. also whenever one of my friends join the server i can't see it for some reason, i tried clearing my favorites list and deleting clientregistry.blob but it's not working, any ideas? :ph34r:

thanks
