What the source record says
5319 Enterprise Dr, Lockport, NY. Built by Yahoo in 2010 (opened at 155,000 sq ft, expanded since); campus totals 409,200 sq ft / 43 acres SHARED with the separate H5 Buffalo II building (~0.25 mi away — see that record). H5 Data Centers acquired both Lockport buildings from Yahoo in a sale-leaseback deal that closed Dec 30, 2024 ($49M reported); Yahoo signed a 5-year leaseback and remains a tenant on-site (140 staff retained, 15 transferred to H5). Now multi-tenant Tier III colocation, though no tenants beyond Yahoo are independently confirmed. Critical power was 16 MW as of 2014; current total post-expansion not independently disclosed, so capacityMw is deliberately omitted rather than guessed. Coordinates are a campus-level geocode (ConnectBase), not a per-building parcel pin.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.
