i took it down a week ago cause it was empty but put it back up this weekend.
its empty cause nobody stays on long enough to wait for others to join.
i've found that dedi servers don't really work out all that well
host it sparsely on your own, invite a bunch of people from steam, ride the wave of players until it goes down to like 3 and shut down. that's what i do when i host and it's great
