Common questions about data centers in San Francisco, CA, answered from the directory's records for the 12 verified facilities cataloged here. Each answer draws on the same source-attributed data that powers the directory tables and operator rankings on this page, with every figure traceable back to the public sources documented for each individual listing. Questions cover facility counts, operator concentration, geographic distribution, and the data sources backing the San Francisco listings.

Every facility on this page has been compiled from the directory's 15 source datasets, including operator filings, regulatory disclosures, and industry databases, and cross-checked where more than one source reports it. ITAMG matches records by name, address, geographic coordinates, and operator identity, then collapses duplicates into a single canonical entry. Where a facility hosts multiple providers, the Index reports the facility operator, which may differ from a provider named in the facility's name. A facility appears here only when two conditions hold. First, the building must be locatable on a map by either coordinates or a verified street address. Second, the record must describe an actual data center, not a colocation reseller, a telco hub, or a paper-only mention in a financial filing. Records that fail either test are excluded.
