We can't consider additional servers in different timezones because of the close association between the server via InSim and the location of the database. At times the exchange of data is fast and furious, and locating the database in a different location from the X-System software or LFS dedicated server would only serve to introduce problems where, honestly, there aren't any now.
Pings to the server from everywhere in the world, including Australia and the Far East, are very good indeed, thanks to the location of the UKCT hardware and its connectivity to a major internet backbone.
