We track 19 datacenter sites in Wisconsin, deduplicated from 20 building permits and public facility records. Of those, 17 are operational and 1 are under construction. Facility directories report different totals because they count colocation suites and carrier hotels differently, so treat this as what we can evidence from public records rather than a definitive census.
1 sites in Wisconsin have permits indicating construction is under way. Because this comes from building permits rather than press releases, it reflects work that has actually been filed with a local authority.
