What the source record says
Originally constructed in 2008 with expansions in 2011, 2015 and 2017; Tier 3 with 4,500 kW of 2N generators, 6,000 kW of UPS, 9,000 kVA of utility feeds and 1,510 tons of N+1 HVAC; nine on-net carriers. This is the former OneNeck Madison data center — oneneck.com/colocation/data-centers/madison now 301-redirects to ussignal.com, so the operator is recorded as US Signal rather than OneNeck. capacityMw.operational is taken from installed UPS capacity. 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.
