Evidence first, including when the answer is uncertain.

What this site is

A public evidence ledger that remains usable without JavaScript. Campuses, projects, parcels, buildings, operating facilities and provider presences are different units. Company claims stay labeled as company claims.

Broad discovery and reviewed evidence

The national directory is a separate third-party licensed discovery layer. It helps people find possible facilities across all 50 states, but its rows are not DataCenterData findings and do not enter reviewed counts. Reviewed records are narrower because their cited evidence, identity and record unit pass the publication gate.

Corrections

Use the structured correction form. It collects the record or claim ID, field, current wording, proposed wording and primary-source URL before opening a reviewable message to corrections@datacenterdata.io. Accepted changes appear on Changes.

• Primary documents are the evidence that can change a record. Company statements are recorded as attributed claims with the claimant named.
• We do not remove, reword or rerank a record because someone asked, paid or threatened to.
• Every request and its outcome, including declines with the reason, is logged on Changes.
• Response time depends on source access and the scope of the requested change. The public history records accepted material changes.
• Do not send confidential material. This is an editorial evidence desk, not an audit, listing service or takedown shop.

Featured claims receive a second source check by a reviewer who did not write the original record. This is an editorial check, not an outside audit. Verdict changes appear on Changes with the old value, the new value and the reason.

Source retention

Published JSON keeps the source URL, source type and retrieval or review date used for the current finding. Light source checks record success and error timestamps in the source registry. They do not rewrite published counts.
