As you may have already noticed, we are currently initiating rolling restarts for all realms. These restarts first began at approximately 9:15 AM PST and will continue until each realm has been restarted. We anticipate each realm being down approximately 15 minutes.
Thank you for your patience as we look to complete this process as quickly as possible.

We've received reports regarding a number of Auction Houses returning the "Internal Auction Error" message when used. We are currently investigating this issue and hope to provide a resolution as quickly as possible. Updates will be provided within this thread as more information becomes available.
