Some testing has shown that the server machine itself is up but the 911/em4 server browser program is down at the moment. As suggested above you can use hamachi. With hamachi you join a network containing other people who you want to play with or create your own and have other people join yours. You can join a hamachi network by going to Network->Join an existing network in hamachi and entering the network name and password, if there is one. When you are ready to play a game you simply host the game as usuall and then have the other people go to the Join Game tab of 911/em4. Then they must hit the left/right arrow buttons next to "internet" until it says "direct ip". In the ip address box you type the hosts hamachi ip address, which can be obtained from the hamachi program itself and usually starts with a 5, and then hit the join button and it will connect to the game. Once this is done everything else works like it usually does. Note that with hamachi you do not need to configure port forwarding or anything on your router, you just have to allow the game through your firewall.
