Из фака евы.7.5 How are the servers set up and how does the server architecture work?
There is a centralized server cluster, located in London, with several proprietary proxy (slave) servers. The proxy servers have dedicated bandwidth to the central cluster. The proxy servers take some of the load off the game logic servers in the cluster by doing data integrity checks and virtual multicasting, making them – in a sense – a software router.
This server architecture, together with clever game design, allows us to have more players, distributed over greater geographical distances, together in the same world, breaking records held by our predecessors in the MMOG genre.
