#1 - March 31, 2016, 2 p.m.
I've tried:
Stormheim
Val'Sharah
Highmountain
Dalaran
Class Hall on my Warlock, Druid, Rogue, and Priest.
The personal instance of the Stormheim intro
And none of those servers are working. The only place I'm able to get into is my Mage class Hall. Not much I can do there. I can't even see if I can get into Azsuna. But I assume not.
