Iron Mountain Data Centers is the colocation division of Iron Mountain Incorporated (NYSE: IRM), the storage and information-management giant, and it sells rack, cage, suite, and wholesale-hall colocation space to enterprise and hyperscale customers rather than building its own cloud service. As of 2026 the unit operates a global portfolio described on its own site as spanning more than 30 locations and roughly 1.4GW of capacity across North America, Europe, and Asia-Pacific, including underground campuses in a former limestone mine in Boyers, Pennsylvania and an underground complex in Kansas City. It has grown largely through acquisition — buying IO Data Centers (Phoenix, Scottsdale, Edison NJ, Columbus OH) in 2018, EvoSwitch in the Netherlands the same year, a Keppel facility in Frankfurt in 2021, a Madrid campus from XData Properties in 2022, and taking full ownership of its India joint venture with Web Werks in 2025. Recent expansion has leaned into AI-ready campuses, most notably a 42MW two-building campus under construction in Chennai, India.
