We are currently trying out two hosts in Asia to find out which would be the best for everyone.
The first one is Singapore and the Beta server has been hosted there for a while.
Today we have introduced a Beta Server in Hong Kong as well. Just update your Beta client (Installation guide : viewtopic.php?f=67&t=24156) and you will have the option to chose between both of them on the game's launcher.
Please let us know which fits the best to you (regarding latency mostly).
