This is a list of servers that people have said are available for CSL matches:

If you wish to use your own server for a match, please install and use the CSL.cfg file on your server.

Please note: To get the partial admin menu up on the CSL server, just type admin into the console. Here you can set tournament mode, gravity and change map. You will need to be registered manually by Chimoo, so if you are not registered yet, badger him.
