Recently Kaivax, a Blizzard Community Manager, posted on the WoW Classic forums that they are postponing their global stress test. This was originally scheduled for next week, however he states that while the launch date is still on track they are not quite ready yet for the global stress test.
We’re hard at work preparing for the launch of WoW Classic, and we’ve reached the conclusion that we’re not quite yet ready to do our Global Stress Test (previously scheduled for next week). While we’re still on track to launch WoW Classic on August 27, we need a bit more time before this final pre-launch worldwide test.
We’ll have a more definite date Soon™ and we’ll post it here as soon as we do. Thanks for your patience!
