Three residents of Mount Pleasant, Wisconsin, have initiated a class action lawsuit against Microsoft's Fairwater Data Center, alleging that the facility generates excessive noise, thereby creating a public nuisance and diminishing property values.

The complaint, filed in federal court, argues that the persistent loud noise prevents neighbors from fully utilizing and enjoying their properties. This legal action highlights ongoing community concerns regarding the operational impacts of the data center.

In response to the complaints, Microsoft issued a statement on June 18th indicating that its engineering team had investigated the reported humming sound and subsequently implemented noise mitigation measures. The company believes the issue has been "fully resolved" but has committed to continue monitoring sound levels at the site.
