Ark Tucson Data Center is an operating Ark Data Centers data center facility in Tucson, Arizona. Ark's operating Tucson physical facility, opened in 2013, with current capacity separated from historical expansion claims. The retrofit records facility power capacity: 2072 kW; conditioned data center area: 20,000 sq ft. Utility service, UPS, standby generation, cooling, facility power and IT load are kept in their source-defined scopes rather than collapsed into one capacity number. Where reliable public evidence for ownership, project financing, permitting, tenants or water arrangements was not established, Cartis records the research gap explicitly instead of inferring a fact.
