A national denominator is not ready.Published rows use different record units and evidence layers. Indiana and Ohio, for example, separate large-project or campus records from physical facilities because the inventories overlap. Adding incompatible rows would create a precise-looking but misleading U.S. total.

History is data—not another facility

The first cross-state lifecycle register preserves nine dated acquisitions, energizations, groundbreakings, approvals and expirations. It shows why names and statuses cannot simply be overwritten: DataBank’s former 365 Data Centers operator, STACK’s acquired New Albany campus, and Hammond’s expired expansion all belong to stable entities.

What “every” can honestly mean

We can target every evidence-identified facility, project and historical lifecycle record after a dated audit of operators, government records, dockets, permits, tax records, archives and directory leads. We cannot prove that an undisclosed private server room does not exist. Completeness is therefore a published audit boundary—not a marketing adjective.
