The providers in this list
All 70 providersHow to read the columns
Methodology- Liquid methods
- The liquid cooling methods the provider names: direct-to-chip, rear-door heat exchanger, immersion.
- Rack density kW/rack
- Published supported rack-density threshold or upper figure. Read Density basis for lower bounds, configuration and site restrictions; this is not a measured universal maximum.
- Model
- How the provider sells space. Retail: cabinets, cages and suites to many tenants, usually with interconnection. Wholesale and hyperscale: whole halls, buildings or build-to-suit campuses leased by the megawatt. Retail and wholesale: both, as the provider describes itself.
- Data centers
- Provider-reported data center or location count. Read Count basis for buildings versus campuses, operating/development status, snapshot date and overlap. Campus-only counts use the separate Campuses field.
- Built MW
- Operating capacity in megawatts as the provider publishes it, usually critical IT load. Where only a combined figure exists it goes in 'Incl. development' instead.
- Incl. development MW
- Published platform scale including development, planned capacity or full build-out potential. This is not pipeline alone. Read Capacity basis for the exact definition, date and exclusions; figures are not directly comparable.
- Key markets
- Flagship metros or countries named on the provider's own pages. Not a full location list: open the provider's site map for that.
