For the North American subscribers, your restarts are expected to begin on Thursday, July 31 at 5:00 a.m. PDT. The Oceanic Realms will be getting their restarts on Friday, August 1 at 5:00 a.m. AEST (July 31, 12:00 p.m. PDT).

The realms are expected to be down for no longer than 15 minutes, with the entire process lasting just an hour. Bornakk didn’t give any exact details on the wow gold nature of the hotfix. That’s all the information we have for the moment, though you’ll want to drop by again in case we run into any related updates. And lest we forget, you’ll want to log out at the closest inn before the restarts begin to avoid any unexpected problems.
