Maintenance Schedule Changed -- 15 January

Hello. In order to address an unexpected issue with the Visions of N’Zoth content update, we’ve moved the window for this week’s maintenance. It will now begin in this region at 6:00 a.m. CET tomorrow, 15 January. As usual, this should not affect WoW Classic, which will see realm restarts at 3:00 a.m. CET. Thank you for your understanding!
