Sometimes, when Gametracker shows the server as down, and it's actually running, attempting to join the server will cause your client to crash. I usually notice this and restart the server within an hour or so, but you can also contact me to report the problem. See the contact info on jdrgaming.com.
2017Feb26: occasionally Gametracker shows the JDRGaming BF2 server as 'Dead' when in fact it is running normally. The problem usually begins in the evening and resolves itself by the next morning (Pacific time). The server can be joined during this time. The issue is being investigated.
