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.
Just had a word with the friendly server provider www.e-frag.co.uk about the time which the server restarts.
They are going to set the time forward an hour, so in the UK it will reboot at 6am, which mean that people from the USA who were being disconnected at 11pm, wont be until midnight.
Due to way games are not 100% perfectly programmed, rebooting is an essential way of keeping the server top quality, but hopefully this will help strike more of a balance between the timezones.
