Gaines Township (Grand Rapids area), Kent County, MI
Switch Pyramid campus (former Steelcase Pyramid)
Why this stage: Switch's 2021 Form 10-K says the Switch PYRAMID data center opened in June 2016 with up to 10 MW available and 99% utilization. State air permits and a Renaissance Zone cover the campus. None of these records names Hot Aisle, and all campus figures predate Hot Aisle's October 2023 founding.
