Blizzard Entertainment has revealed the scale of the server infrastructure behind World of Warcraft: Forever, confirming that the MMORPG’s launch was supported by 3,924 virtual machines, 70,480 CPU cores and 251,136GB of memory. The figures provide a detailed look at the computing resources required to support one of the franchise’s largest online launches.
The company disclosed the specifications through the official World of Warcraft account on X on November 5, 2026, one day after Forever launched. The announcement followed reports of a relatively smooth opening, with players experiencing fewer widespread server disruptions than those associated with some previous major World of Warcraft releases.
The deployment’s total memory capacity exceeds 251TB when expressed in decimal units, while its 70,480 CPU cores represent computing resources distributed across thousands of virtual machines rather than a single physical system.

Dividing the reported resources across the 3,924 virtual machines produces an average of approximately 18 CPU cores and 64GB of RAM per instance. However, Blizzard has not disclosed whether those virtual machines use identical configurations or how their workloads are distributed.
The figures also do not identify the underlying processor models, physical server count, memory technology or hosting provider. As a result, the precise hardware configuration and total infrastructure cost remain unknown.
The scale becomes particularly interesting when compared with Blizzard’s historical World of Warcraft infrastructure. In 2009, the company disclosed a worldwide deployment spanning 10 data centers and 13,250 server blades, representing approximately 75,000 CPU cores and 112.5TB of memory.
Compared with those historical totals, Forever’s reported infrastructure uses approximately 6% fewer CPU cores while providing more than twice the memory capacity. However, the deployments are not directly equivalent: the 2009 figures described World of Warcraft’s broader worldwide infrastructure, while the new figures concern Forever’s launch.
Modern server processors also deliver substantially different performance from hardware available in 2009. Consequently, comparing CPU core counts alone cannot establish the relative computing power or efficiency of the two deployments.
World of Warcraft: Forever launched on November 4 as a new version of Blizzard’s long-running MMORPG. Its arrival also introduced official controller support, including a Gamepad (Alpha) implementation intended to make the game more accessible to controller users and handheld PC players.
Unlike World of Warcraft’s traditional realm-based structure, Forever uses selectable gameplay rulesets and layering technology to distribute players across different instances of the game world. This arrangement allows the service to manage large populations without requiring players to select conventional individual realms.
The launch has received positive reports regarding overall server stability, although the experience has not been entirely problem-free. Some players have reported issues with layering, including areas appearing unexpectedly empty and group members being separated into different instances.
Blizzard’s infrastructure disclosure does not establish how much of the available computing capacity was used during peak activity, nor does it provide a breakdown of resources allocated to particular regions or gameplay systems.
The company has also not disclosed a precise peak concurrent player count alongside the hardware specifications. While the figures demonstrate the substantial infrastructure supporting Forever, they cannot independently determine how many players were online simultaneously or prove that server capacity alone was responsible for the comparatively stable launch.
For PC gamers, the disclosure offers an uncommon quantitative look at the server-side requirements of a major MMORPG release, where thousands of virtualized computing instances and hundreds of terabytes of memory help support a shared online world.
