Cannot connect to 2584 (needs reboot)

after the reset this morning I was not able to connect to the server. I’ve restarted the xbox, reset my XB mac address, tried connecting to other servers (successful), had my brother log into my account from his house (successful), reset my modem / router. The only thing I can’t test is what happens if I change my IP, my ISP doesn’t let you change it.

This same thing has happened to a friend of mine and it took gportal resetting the server to resolve. Please help.
