RIFT players, it turns out that several of the game's servers have been converted over to trial servers. Naturally, it makes players instinctively fearful that it's the first step toward server shutdowns and closures.
But that's not quite what's going on. As explained by community manager Elrar quite some time ago, trial servers are lower-population servers that are essentially being put to one side for large-scale trial programs. Character creation for subscribers is disabled on those servers, and there's a message encouraging you to move to another server with a free transfer, but it's not a shutdown, just a ramp-up to a larger trial period for non-subscribers.
According to Rift Junkies, a total of 11 servers are seeing the trial tag applied, and players are encouraged to move off these servers by January 18th. If you've got a character on Belmont, Galena, Atrophinius, Crucia, Alsbeth, Estrael, Shadefallen, Sunrest, Freeholme, Dayblind, or Faemyst, now would be a good time to start planning for greener, non-trial pastures.
