Source-reported capacity; not metered consumption. Review underlying documents and notes. Planned capacity may include future phases and is not added to operational capacity here. The source may use facility, grid-feed or IT capacity definitions; consult the linked documents.
Coordinate precision is a source label, not an independent parcel survey. A marker does not confirm utility territory or establish an effect on residential bills.

Source notes
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 redirected to ussignal.com as of August 2026, so the operator is recorded as US Signal rather than OneNeck. The operational capacity is taken from installed UPS capacity. Coordinates are an address geocode.
