Notes on the record
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.
