Map sources and method

The state outline is adapted from the U.S. Census Bureau 2025 cartographic boundary file. Facility coordinates are adapted from Compute Atlas by Edward Kubiak, edition 1.34.1, under CC BY 4.0. Outline and markers use one geographic projection before any explicitly disclosed readability offset. Exact singleton source anchors are never moved. A one-kilometre boundary tolerance prevents the simplified 1:20,000,000 outline from hiding legitimate border-area source points; farther conflicts are disclosed, not clamped. DataCenterData groups source-reported city coordinates only within a bounded map radius; the outline does not validate a facility record. Some locations in this layer are reported by the provider as derived from OpenStreetMap (© OpenStreetMap contributors, ODbL, https://www.openstreetmap.org/copyright) and Epoch AI (CC BY 4.0).

Separate layer

Also listed by operators

Sites that operators list on their own websites and that are not rows in the licensed directory above. They are kept apart and never added to the licensed rows.

16 of these sites have no supported coordinate. The map does not invent a pin or a metro placement for them.

Where the records were checked

Statewide audit pending

A few checked sites

This is not a list of every data center in the state, and the number here is not a count of them. There are almost certainly more.

Statewide coverage is not complete. The records below are sourced; a full statewide count has not been published.

State research audit window ended 12 September 2026. Individual records and claims below show their own evidence dates and may be newer.

Coverage review was due 21 October 2026; no later coverage review is recorded as of 3 November 2026.

1 independently source-linked project/campus record; 0 independently source-linked facility/building records; 0 attributed or unresolved rows. These counts use different units and must not be added together.

Source families checked, selected records and remaining gaps

These notes name selected records, say which kinds of public evidence were checked and show what remains missing. They do not add anything to the published counts.

Local evidence by place

Licensed and operator listings, reviewed records, answers and local policy for each place. Listings overlap and are not added; a place without a line here has no published local evidence.

No local evidence answer, reviewed record or local policy record is published for Avondale, Buckeye, Casa Grande, El Mirage, Eloy, Glendale, Goodyear, Laveen, Tonopah. Their listings above are source listings to investigate. No statewide evidence answer is published for Arizona either; statewide rules are under Policy tracker below.

1 Arizona answer is not tied to a published record, so it is not placed here: Arizona answers.

Federal and multistate instruments that cover all or part of Arizona

These federal, reliability-organization and multistate grid or utility instruments are stored once and listed for every jurisdiction they name. They do not add to the record count, in-effect total or map shading for Arizona. Territorial coverage does not establish that an instrument applies to any particular site, utility or project.
