The providers in this list
All 70 providersHow to read the columns
Methodology- 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.
- 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.
- 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.
- Countries
- Provider country coverage as published or counted from its location list; may include development and announced projects. Read Count basis and Key markets for stage and scope.
- Liquid cooling
- The provider offers or supports liquid cooling (direct-to-chip, rear-door heat exchangers or immersion) for colocation customers, on a page cited in the record's sources. Blank means no such offer was found on the pages read.
- 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.
- Ownership
- Who owns the provider: a stock listing, or the named private owners from the provider's own pages, filings or the deal announcement.
