About these records and their limits
These are 234 source records, not a complete or deduplicated world census. A campus may contain several buildings, and sources may describe different phases or the same place. A missing result does not mean no data centre exists there.
Epoch's owner field attributes AI hardware, not necessarily the facility owner or operator. Detailed records keep facility operators and owners distinct. Imported Epoch records have no whole-record lifecycle stage or sourced map coordinates in our current extraction. Separately dated building reports describe some buildings, not an entire completed campus. The building-evidence filter is independent of Recorded stage. Future projections are excluded. 80 existing records carry separately dated, source-reported address/location fields; these do not establish a building/phase identity, map coordinates or operating status. Some values are localities or plus codes rather than street addresses. Display normalises whitespace and dash typography; exported fields retain the source values. Other addresses are not recorded here, not proven absent. Stage not recorded must not be read as unbuilt. Operating does not establish compute available to buy.
Data centre, campus or AI project?
A data centre houses computing infrastructure. A campus can group buildings and shared infrastructure. AI describes the computing use, rather than a separate lifecycle stage. We retain each source's scope and do not infer a building count, operational status or available capacity from a project name.
