I don't see it, but maybe you took it down.
If the server is not visible on the Internet (assuming you used the sample server.cfg included with the Asteroids Mod) it is most likely due to a firewall\router problem.
Turn off software firewalls like ZoneAlarm, and open ports 29060 to 29062 and 29070 to 29081.
Your server will always be Local to you (because you are connecting locally to it) even when others see it under Internet. For the same reason, on ASE it won't be in the Internet section, it will be under Special-> LAN servers to you.
The next time you have it up, go to
