Since there is something wrong with Activision's master server gizmo today, so that you can't see any servers, there's still a way to get into our server.
1. Start up cod4
2. Press your tilde ~ key to bring down the console.
3. In the console type this:
/connect 8.9.4.83:28960
(you don't have to type in the :28960 part, but it seems to get me into the game quicker)
For our other cod4 server, the IP is 8.9.4.85:28960
