No lawsuit, organized opposition, or contested hearing over EdgeConneX Madison (MAD01) in Madison, Dane County, Wisconsin appears in the sources this registry tracks.

Notes on the record
Carrier-neutral edge colocation established in 2015 as a retrofit of a 115,000 sq ft building constructed in 1999; 7,800 sq ft of facility with 2,650 sq ft of raised floor, 30-inch plenum, N+1 CRAC, capable of 20+ kW per cabinet and 600+ watts per sq ft. No megawatt figure is published by the operator, so capacityMw is omitted. Coordinates are an address geocode.
What the record does not establish, and the document that would
In every fight on our tracker the decisive fact came out of a public records request. These are the requests for this site.
- Power capacity in megawatts
- Cooling method and water use
- Tax abatements or other public subsidy
- Permanent jobs promised
- Land area
- How the community has received it
- Which utility serves it
Which document closes each gap
- Power capacity in megawatts
- The utility's large load service agreement, the interconnection request in the grid operator's queue, or the electrical site plan in the permit file.
- Cooling method and water use
- The water service agreement, any groundwater appropriation permit, and the mechanical narrative in the site plan.
- Tax abatements or other public subsidy
- The abatement, PILOT, or development agreement approved by the county, city, or development authority, and the state's data center sales tax exemption certificate if one was issued.
- Permanent jobs promised
- The economic development application or incentive agreement, which usually states a job commitment and a clawback.
- Land area
- The rezoning application, the plat, or the deed recorded with the county.
- How the community has received it
- Planning commission and governing body minutes, public comment records, and any petition or lawsuit filed in the county.
- Which utility serves it
- The electric service agreement or the utility's filing with the state public utility commission.
