BREAKING: Wisconsin Residents Sue Microsoft, Claiming Its New Fairwater Data Center Produces Excessive, Nonstop Noise That’s Disrupting Sleep And Ruining Their Ability To Enjoy Their Own Homes 🤖💥
Three Sturtevant, Wisconsin residents filed a federal class-action lawsuit against Microsoft on July 1, alleging that its newly operational Fairwater data center in nearby Mount Pleasant emits excessive, constant noise that’s damaging their property and daily lives. The suit, filed in the U.S. District Court for the Eastern District of Wisconsin, specifically points to diesel generators and HVAC equipment, including chillers, cooling towers, and condenser fans, arguing the facility fails to use adequate acoustic barriers to stop the noise from spilling onto neighboring properties. Named plaintiff Garrett Ostergaard says the noise forced him to change his work shift entirely, while fellow plaintiffs David and Joy Wade say they can no longer enjoy their backyard deck the way they used to.
Microsoft doesn’t dispute that a noise issue existed. Back in April, the company investigated complaints and traced a disturbing humming sound to the data center’s cooling fans, and in a June 18 blog post, it announced mitigation measures were in place, with plans for additional sound reduction components. Microsoft has since told the Journal Sentinel its fixes “fully resolved the issue,” a company characterization that stands in direct tension with residents choosing to file a federal lawsuit just weeks later describing the same disruption as ongoing.
This case adds to a pattern of friction between Microsoft and Wisconsin communities over its AI infrastructure buildout. A separate 2025 dispute saw Milwaukee Riverkeeper sue the City of Racine after officials withheld public records for over six months on the data center campus’s projected water use, eventually revealed to be roughly 8.4 million gallons annually, while Microsoft also canceled an unrelated nearby data center project near Oak Creek in October 2025 following community pushback.
