Microsoft hit with class-action lawsuit over "unreasonable and excessive noise" from datacenter

Microsoft faces a class-action lawsuit filed on July 1 2026 alleging unreasonable and excessive noise from its Fairwater datacenter in Mount Pleasant Wisconsin. The datacenter unveiled in September 2025 is the largest and most advanced site featuring NVIDIA GB200 GPUs each rack processing 865000 tokens per second. Microsoft says noise levels comply with local ordinances and that it has investigated the sound conducted tests and placed noise mitigations which neighbors say resolved the issue.
