We are currently experiencing an issue with the Battle.net Authentication servers which is preventing players from being able to successfully login to World of WarCraft and StarCraft II. Our server technicians are hard at work to resolve this matter as soon as possible. Please stay tuned to this threads for any further updates as they become available.

Authentication is now once again functioning properly, and you should now be able to log into World of Warcraft and StarCraft II. Have fun!
