Filings and reviews: dated data center events
Applications an official body recorded as filed, received or complete, and notices opening an official review. A filing or review is not an approval.
About these streams
Three different things, kept apart. Facility and project events happened in the world on the date the source gives. Evidence updates are DataCenterData publishing records; they are not events at a facility. Corrections to what DataCenterData published live in the corrections history, the corrections authority.
No reviewed milestones match these filters. This does not establish that no activity occurred.
