Blizzard ran WoW: Forever’s launch night on 3,924 virtual machines with 251,136 GB of memory and 70,480 CPU cores. The official World of Warcraft account posted the numbers on X later that evening, November 4, in a post that opened with “*Slaps Roof of WoW: Forever*” and “This baby is running on:”.

That is roughly 251 terabytes of RAM. Blizzard has not said how many people were playing on it.
Each of the 3,924 machines gets 64 GB and about 18 cores
Split evenly, the fleet works out to exactly 64 GB of memory per virtual machine and just under 18 CPU cores each. That’s our own arithmetic, though. Blizzard didn’t post per-server specs, so the real setup behind each world could look quite different.
Several things are still unknown. The post doesn’t say:
- where the machines run, or whether this is Blizzard’s own hardware or a cloud provider
- whether the 70,480 cores are physical cores or virtual ones
- whether the totals cover every region or one snapshot of launch night
- how many players logged in, or the peak concurrent count
WoW: Forever had almost no login queues on launch night
The hardware seems to have done its job. Players on the WoW: Forever subreddit and on stream reported almost no login queues, disconnects or lag on launch night, a big change from the beta, which Blizzard admitted it “wasn’t ready” for. WoW: Forever puts players on large mega-servers spanning several regions instead of dozens of separate realms, so the capacity has to sit behind a few very large worlds.
Boats, zeppelins and empty layers were the two launch problems
The launch wasn’t flawless, and Blizzard said so the same night. WoW Classic and Forever developer Josh Greenfield posted a launch-night update covering the two issues players hit most:
Transports – we had some issues with the service that manages transports like boats and zeppelins. As a temp fix we spawned some portals to get us through the night. We’ll have a proper fix in the morning and the portals will be removed.
Layer populations – we are aware some zones feel more empty than they should. Tomorrow we’ll be tweaking some numbers to make things feel more lively. Sit tight!
Spawning portals in a few hours so players could keep moving, then telling them plainly what would change the next day, is the kind of launch-night communication players usually ask for and rarely get. Greenfield signed off with “Thanks for everyone making this a great, super smooth launch!” and joked that he was heading home to “go to sleep”, and was “Totally not playing WoW Forever until 3am.”
WoW: Forever is the third permanent version of Azeroth, alongside modern WoW and Classic, and it’s included with an active World of Warcraft subscription or Game Time. If you’re still playing through launch week, Blizzard’s free Pouch of Violet Dust toy is available until November 12.
