Uptime Institute Tier IV data centers in France

Facilities in France 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.

11 of the 186 facilities we track in France publish Tier IV — 10 operators, 28 MW of published IT capacity, 11 operational. Cities: Mougins, Aubergenville, Saint-Maurice-la-Souterraine, Rillieux-la-Pape, Saint-Jean-d'Angély, Reventin-Vaugris, Ivry-sur-Seine, Magny-les-Hameaux, Verlinghem, Saint-Apollinaire.

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.
