It looks like Blizzard is closing down one of the most popular World of Warcraft private servers, after sending cease and desist letters to their hosting company. The servers are set to close April 10, at 23:00 server time.
Named Nostalrius, the servers run an older version of World of Warcraft – specifically from 2004 to 2007 – before the game got any of its expansions.
At its peak, the server Nostalrius had 800,000 subscribers, with some of them also said to be official World of Warcraft subscribers. At that time, the server also had 150,000 active players. This data comes from a petition penned by the server team, which currently has over 39,000 signatures.
The team behind the project has 30 volunteers, who were apparently trained in multiple different fields to meet the needs of the server – including development, software validation, and customer service.
The Nostalrius servers were about to implement the 40-man raid Ahn`Qiraj, which was one of the final raids to launch for original World of Warcraft, before its expansions released.
