Malfurion/Trollbane/Grizzly Hills/Lothar/Gnomeregan/Moonrunner/Kael’thas/Ghostlands crashed too. I brought it up in a Slack channel and another user remarked that WoW hasn’t been the only game having server issues today (Battlefield 2042). Could potentially be a DDoS attack, but we’ll have to wait and see.
It’s the central time zone servers too. Just like everyone else posting, I got dc’d, sent to the queue, and errored out at the retrieving realm list. I also get the error code 51900324 along with the message to contact technical support.
