Facts
Source per value- 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.
- Retail and wholesale 1
- 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.
- 30 1
- Metros Number of metros or markets the provider says it serves, as it counts them.
- 11 1
- 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.
- 1 1
- 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.
- Not published
- 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.
- Not published
- 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.
- Not published
- 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.
- Not published
- 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.
- Not published
- Liquid methods The liquid cooling methods the provider names: direct-to-chip, rear-door heat exchanger, immersion.
- Not published
- Interconnection The provider's interconnection offer as it names it: software-defined fabric, cloud on-ramps, internet exchanges and carrier-neutral meet-me rooms.
- Open Cloud Exchange (software-defined); cloud on-ramps; 44,000+ customer interconnections 1
- Networks on-net Carriers and networks the provider says are available across its platform (a stated '1,000+' is recorded as 1,000). Counts differ in what they include, so compare orders of magnitude.
- 500 1
- Certifications Certifications and attestations the provider lists (ISO 27001, SOC 1/2, PCI DSS, HIPAA, Uptime Institute Tier and others). Coverage often varies by site; the source says which sites hold which.
- Not published
- Published price $/kW/mo Public list price per kW per month, where the provider publishes one. Converted from a per-cabinet monthly price only when the source states the cabinet's kW. Almost every provider quotes per deal, so this is usually blank.
- Not published
- Ownership Who owns the provider: a stock listing, or the named private owners from the provider's own pages, filings or the deal announcement.
- American Tower (NYSE: AMT) 1
- Campuses Published campus count, separate from individual data center buildings. A campus can contain several facilities.
- Not published
- Count basis What the footprint count measures, its snapshot date where available, and any parent/platform overlap.
- 30 data centers in 11 US markets, per the About page. 1
- Capacity basis Exact basis and date of the MW figure: operational, leasable, construction, contracted, planned or potential. Not a measure of vacant availability.
- Not published
- Platform overlap Parent, subsidiary or joint-venture relationships relevant to avoiding double counting. Directory row counts are not independent operator totals.
- Not published
- Density basis Scope, configuration and threshold qualification of the published kW per rack figure.
- Not published
- Deployment example A sourced facility example with its own scope, kept separate from platform capacity totals.
