Uptime Institute Tier IV data centers in United States

Facilities in United States that publish Tier IV certification. Fault tolerant: the facility survives any single unplanned failure without impact on IT load. Rare, expensive, and usually reserved for financial and government systems.

6 of the 1332 facilities we track in United States publish Tier IV — 6 operators, 0 MW of published IT capacity, 5 operational. Cities: Mililani, HI, Starkville, Fort Pierce, New Albany, Grapevine Texas, Olathe Kansas.

For context, wholesale colocation in United States is benchmarked at $196 per kW per month (CBRE, North America Data Center Trends H2 2025), and commercial electricity at $0.117 per kWh — certification rarely changes the rack rate, but it narrows the shortlist.
