A few hours ago we only knew, that the Hardcore Realms would go live on 08/24. Last night Blizzard announced the schedule for the global release.
Pack your bags for adventure—realms go live globally at 3:00 p.m. PDT on August 24.
Face Azeroth’s dangers in WoW Classic’s Hardcore realms and see just how far you can go. You only have one life to live, and the Spirit Healers won’t be there to send you back out into the world of the living when you die. Death is permanent, and once you’ve been bested by the environment (or even other players), you’ll need to dust yourself off and create a new character to try again.
