    "Rows are the deployment records on this site. Each carries a stage taken from the most recent source, and the stage history is on the record.",
    "Stage is deliberately four values — operating, deploying, planned, pilot — because a finer scale would imply knowledge the sources do not contain.",
    "Capacity is quoted as the source states it. Where a project reports IT load and facility load differently, the record says which.",
    "A project with no source is not published, so it is not in this file."
  ],
  "limits": [
    "Operators disclose selectively. A market with few rows may be under-reported rather than under-built.",
    "Announced capacity frequently changes and is rarely restated publicly. Treat a figure as of its review date, not as current.",
    "Supplier attribution is limited to what a source names, so a project may involve suppliers this file does not list.",
    "Colocation projects are recorded at the facility, not per tenant, because tenant loads are almost never public."
