You'll probably need to portal there, as there server will likely boot you otherwise, but if you have portalled, here's the IP:
69.80.198.71:5121
Go to direct connect in gamespy and enter the IP, and that should do it. I'm also assuming you have all the haks, even the old ones, two of which apparently I don't have, since it won't let me log in. And those two aren't available to download except if you download the old all-in-one bundle, which by the time you're done downloading that, the point behind going to the planes server will be mostly if not all the way over, so I hope you have those old v2 files.
