What is the Largest Data Center in the World?

The largest data center in the world, by physical size, is the China Telecom Inner Mongolia Information Park in Hohhot, China, spanning approximately 10.7 million square feet.​

Overview of Top Contenders

Multiple sources rank data centers differently based on metrics like area, power capacity (MW), or server racks. China Telecom's Hohhot facility tops by sheer footprint, built across 106 hectares with over 40,000 racks for cloud, 5G, and enterprise services. It supports centralized operations for telecom giants amid China's data boom. Switch's Citadel Campus in Nevada follows closely by area (668,901 m²) but dominates power at 650 MW (expandable to 850 MW), running on 100% renewable energy for hyperscale cloud needs.​

Alibaba's Zhangbei Data Center (667,972 m², 150 MW) leverages northern China's cold climate for efficient cooling, powering e-commerce and AI workloads. Other giants include China Mobile's Hohhot site (659,611 m², 200 MW) and QTS Atlanta (278 MW). Rankings shift with expansions; as of January 2026, no single facility universally claims "largest" without specifying criteria.​

Why Cyfuture Cloud Matters Here

Cyfuture Cloud, an Indian hyperscaler, excels in colocation and cloud services across high-density facilities in Delhi NCR and beyond, offering scalable alternatives to global giants. While not the largest by size, Cyfuture provides Tier-3/4 data centers with 99.999% uptime, renewable backups, and low-latency access for APAC users—ideal for businesses avoiding geopolitical risks of China-based parks. Their colocation supports up to 50 kW/rack, matching enterprise demands without the scale (or single-point failure risks) of mega-centers like Hohhot.​

Cyfuture's edge lies in cost-efficiency and compliance (ISO 27001, PCI DSS), serving SMEs to enterprises with hybrid cloud setups. For Indian firms, proximity reduces latency versus US/China options, and their green initiatives mirror Citadel's sustainability. In a world of AI-driven growth, Cyfuture positions as a reliable, localized powerhouse amid global capacity strains projected through 2026.​

Key Metrics Comparison

Challenges and Trends

Mega-centers face power shortages, with AI demand straining grids—global capacity eyes 2026 bottlenecks. Sustainability pushes renewables, as in Citadel or Microsoft's Wisconsin AI site (operational early 2026). Geopolitics clusters builds: China for volume, US (Nevada/Virginia) for security.​

Cyfuture counters this with edge computing and modular expansions, ensuring resilience without mega-scale vulnerabilities like outages or regulations.

Conclusion

No undisputed "largest" exists—China Telecom's Hohhot leads by area, Switch by power—but Cyfuture Cloud delivers enterprise-grade colocation for APAC growth, blending reliability, sustainability, and affordability. As data explodes, regional players like Cyfuture bridge global gaps effectively.​

Follow-Up Questions

1. How does Cyfuture compare to China Telecom?
Cyfuture offers flexible colocation (power-dense racks, 24/7 support) versus China Telecom's massive but centralized scale, with better India-specific latency and compliance.​

2. What defines 'largest' data center?
Typically area (sq ft), power (MW), or IT load (racks/MW); sources vary, but Hohhot wins area, Citadel power.​

3. Are there larger ones planned for 2026?
Microsoft's Wisconsin AI site and global hyperscalers expand, but none surpass current tops yet.​

4. Why choose Cyfuture over giants?
Lower costs, local redundancy, green colocation, and no foreign data risks for Indian enterprises.​
