Uptime Institute Tier III data centers in France

Facilities in France that publish Tier III certification. Concurrently maintainable design: any capacity component can be taken out for service without shutting down IT load. The practical floor for production workloads.

8 of the 186 facilities we track in France publish Tier III — 8 operators, 0 MW of published IT capacity, 8 operational. Cities: Civrieux, Paris, Montreuil, Peltre, Strasbourg, Chambray-les-Tours.

For context, wholesale colocation in France is benchmarked at $190 per kW per month (CBRE, Global Data Center Trends 2026 (17 June 2026), Fig. 5 — Q1 2026, 250–500 kW), and commercial electricity at $0.173 per kWh — certification rarely changes the rack rate, but it narrows the shortlist.
