One campus can operate an early phase while constructing another and announcing a third. Different organizations may describe the same physical capacity as owner, operator, cloud provider or customer, creating double-counting risk. The Stargate and India hub announcements illustrate why dated status belongs to a specific phase and amount. Source date, checked date and power boundary distinguish the reported snapshot from later events; announced megawatts do not automatically count as operating capacity. Counts of factories or access centers require their own definitions and cannot be treated as equal-sized facilities.","specs":[{"label":"Status vocabulary","value":"Operating, commissioning, construction, planned and retired","context":"Apply status to a dated phase rather than an entire ambiguous name."},{"label":"Entity identity","value":"Physical site versus service or organization","context":"Shared ownership and customer claims can refer to one installation."}],"interfaces":[{"name":"Operator and public records","direction":"in","signal":"Dates, identities, capacities and explicit status statements"},{"name":"Curated phase record","direction":"out","signal":"Comparable evidence with unknown boundaries retained"}],"tradeoff":"A smaller verified map is more interpretable than a large collection of incompatible announcements, though it must state its incomplete coverage.","whyAI":"Available AI service depends on the operating phase and access arrangement, not on the largest planned campus headline.","related":["production-ramp-allocation","regional-siting-access","cluster-commissioning-gates"],"sources":[{"title":"Five new Stargate sites","url":"https://openai.com/index/five-new-stargate-sites/"},{"title":"Google AI Hub construction milestone in India","url":"https://blog.google/intl/en-in/google-ai-hub-scaling-indias-ai-infrastructure-and-community-impact/"},{"title":"The EuroHPC Joint Undertaking launches the AI Gigafactories Call","url":"https://www.eurohpc-ju.europa.eu/eurohpc-joint-undertaking-launches-ai-gigafactories-call-2026-07-30_en"}],"scale":"Facility phases to region and world; geography schematic","kind":"architecture","branch":"Global AI infrastructure","subbranch":"Global evidence and resource accounting","mechanism":["Resolve the physical site and identify any separately dated construction or operating phases.","Identify each organization’s role without counting the same hardware again under another name.","Attach capacity only to the phase and status directly supported by the source.","Preserve unspecified IT/facility boundaries and distinguish checked date from the reported event date.","Aggregate only compatible non-overlapping records and display the census’s coverage limits."],"misconception":"A planned gigawatt campus is not a gigawatt of operating compute, and an access antenna is not an equivalent data-center building.","check":{"question":"How should a partly operating campus with an announced expansion be recorded?","options":["As two unrelated copies of the same total","As separate phases with their own status and capacity","As fully operating at its final planned size"],"answer":1,"explanation":"Phase records preserve real progress while preventing planned and operating quantities from being merged."},"science":[{"title":"Status-scoped aggregation","equation":"Cstatus(t) = Σp Cp(t)·1[statusp(t)=status]","explanation":"Cp is compatible capacity for non-overlapping phase p at time t; the indicator selects one status.","assumptions":"Only sum identical units and power boundaries; unknown amounts remain excluded or explicitly unresolved."}],"prerequisites":["cluster-commissioning-gates"],"learningObjective":"Build a capacity record that preserves geography, identity, phase and evidence status.","workstream":"W10","visualFamily":"world-network","engineeringExample":"Synthetic campus has 20 MW operating and a separate 80 MW planned expansion.
