What the source record says
Small downtown Madison colocation facility in a 1972 building renovated in 2008; Tier 3 resiliency with a 280 kW generator, 150 kW UPS, 300 kVA utility feed and 40 tons of N+1 HVAC; five on-net carriers. capacityMw.operational reflects installed UPS capacity — this is a small edge/POP-scale site, not a hyperscale campus. Coordinates are an address geocode.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.
