Mal'Ganis is one of the original servers which was available at launch, 23rd of November 2004, and was one of the big 4 that were down for an extended period of 5 days within the first week due to initial heavy user load on the launch servers. Mal'Ganis is one of the few servers which favors the Horde population slightly thanks to an existing large web community who chose to inhabit the server early on.
