Coverage
Two tiers, stated plainly
We track 966 data centers and filings, last updated August 19, 2026. Coverage runs in two tiers, and reading a result correctly depends on knowing which one your state is in.
Operating facilities: nationwide. Existing data centers in every state, from the public building footprints in OpenStreetMap and the IM3 Open Source Data Center Atlas (Pacific Northwest National Laboratory), plus our own research. If a data center is running near you, it should be on the map wherever you live.
Planning filings: 13 states. The rezonings, permits, development-of-regional-impact notices and utility filings that decide what gets built next are researched county by county in Georgia, Virginia, Texas, Arizona, Nevada, Ohio, Indiana, North Carolina, South Carolina, Tennessee, Alabama, Mississippi, Louisiana. In these states a quiet result means our researchers found nothing on the record. Elsewhere it only means nothing operating is mapped nearby, and the answer page says so.
What a null result means either way: "nothing we track" is a statement about our list, not about the ground. Developers routinely assemble land and file under a shell LLC or a code name, and some counties publish agendas only days before a vote. The alert exists for exactly that gap.

What counts as a project
For the filings tier: a specific site with a public record or credible local reporting behind it, a rezoning or special use application, a development of regional impact filing, an approved permit, a utility large load agreement, a construction start, or a building that is operating. We record "rumored" only when a named outlet reports a named site or applicant; a land purchase alone is not enough. Withdrawn and denied projects stay on the list, marked as such, because they come back. For the operating tier: a facility mapped in OpenStreetMap with a name or operator, clustered by campus.
Getting your state to full coverage
Filings states are added in order of how much is being built and how loud the fights are. If you have a filing we are missing anywhere in the country, send the link to the address in the footer and we will add it with credit.
