Last Month the Japanese try to retrive this mod a little bit more. They played in the at 2pm CET. At the moment the gametracker,com Server Monitorring is off. Hope soon they turn it on. The ranking seems to work.
Ive put the CTF and Battle Park on the the server used for beta testing as it still has some contract left. But its only 14 players, and i would recommend you make the most of the 40 plus player servers while they are still around.
