We track 55 datacenter sites in Arizona, deduplicated from 94 building permits and public facility records. Of those, 25 are operational and 30 are under construction. Facility directories report different totals because they count colocation suites and carrier hotels differently, so treat this as what we can evidence from public records rather than a definitive census.
30 sites in Arizona have permits indicating construction is under way, and the permits that disclose a value total $1.9B. Because this comes from building permits rather than press releases, it reflects work that has actually been filed with a local authority.
29 named operators appear in Arizona, including EdgeCore, NTT, Apple, Amazon Web Services, CyrusOne, Centersquare, EdgeConneX, Compass Datacenters. 64% of sites nationally name an operator; the rest are permits filed by an LLC or contractor we could not resolve to a parent company.
