11:04 p.m. PST - We're aware about two-dozen realms went offline at approximately 10:45 and are investigating the cause. This is also resulting in the majority of realms that are still online not allowing players to completely log in. We'll provide updates as they become available.

11:29 p.m. PST - We've contacted our service provider and they're investigating the possibility that this is an intentional and external disruption.

11:38 p.m. PST - We're seeing some recovery for login attempts and players reporting that they're able to successfully log in.

11:45 p.m. PST - Our service provider has been able to mitigate the issue, and we'll continue monitoring realms throughout the night.

Thanks for your patience everyone.
