ArenaNet is continuing its look at quality of life improvements and feature enhancements that will be coming into Guild Wars 2 with the deployment of the next update. In today's blog post, the team outlines the megaserver structure that will be implemented. No matter what home world players reside on, they will be able to game with friends cross server thanks to the new technology.
The megaserver system means you won’t encounter overflow maps anymore. All maps are now created equal, and the system tries very hard to always make a meaningful choice for you by keeping an appropriate number of maps open at all times. In this way, our megaserver technology can accommodate our large population and its fluctuation around world events.
The megaserver system is a weighted load balancer for players. It aggregates data about you, like your party, guild, language, home world, and the map copy where people you like to play with can be found. Using this data, it ranks all possible versions of a given map by attributing a score to each. You’re placed in the map with the highest score, which is the one with which you have the most affinity.
