As of December 2025, the China Telecom Inner Mongolia Information Park in Hohhot, Inner Mongolia, China, is widely recognized as the world’s largest data center complex by physical size. This massive hyperscale facility spans approximately 10.7 million square feet (about 994,000 square meters), far exceeding other single-site or campus footprints currently operational.
Why Does This Facility Top the List?
Operated by China Telecom, one of China’s leading telecommunications providers, the park serves as a major cloud computing and data storage hub. It features multiple data halls with a power capacity of around 150 MW, supporting internet services, content delivery, and AI workloads. Its remote location leverages cooler climates for efficient cooling and access to renewable energy sources.
The complex includes not just server halls but also supporting infrastructure like offices, warehouses, and staff accommodations, contributing to its enormous footprint. Independent verifications via satellite imagery confirm the scale, though exact data-hall portions vary in reports.
Key Comparisons
For context:
- Switch Citadel Campus (Nevada, USA): Planned for up to 7.2-7.75 million square feet, but the current operational space is significantly smaller.
- Range International Information Hub (Langfang, China): Around 6.3 million square feet.
- Other Chinese facilities, like China Mobile’s in Hohhot, are also massive but fall short in total area.
While U.S. hyperscalers (Microsoft, Amazon, Google) operate thousands of distributed facilities with immense collective capacity, no single site matches this Chinese megastructure.
The Bigger Picture
This dominance highlights China’s rapid investment in digital infrastructure amid surging global data demands from AI, cloud services, and streaming. As AI training escalates power needs, new projects, like planned gigawatt-scale campuses in the U.S., may challenge records soon. For now, China Telecom’s park reigns supreme, symbolizing the shift toward monumental, centralized data hubs powering our connected world.
