Iron Mountain Data Centers is the colocation and data center division of Iron Mountain Incorporated (NYSE: IRM), the storage and information-management giant, and it sells rack space, cages, suites, and wholesale/hyperscale halls to enterprise, government, cloud, and AI customers rather than selling compute itself. As of 2025 the division operates more than 25-30 data centers across North America, Europe, and Asia-Pacific, describing a global footprint of roughly 6 million square feet and about 1.4 GW of capacity, serving over 1,300 highly regulated customers. Its differentiator is a heavy emphasis on regulated-industry compliance (FedRAMP, FISMA High, HIPAA, PCI-DSS, ISO 50001/14001 at every site) plus unusual physical formats, including two facilities built 200+ feet underground in former limestone mines in Pennsylvania and Kansas City.

Iron Mountain markets several of its larger campuses as AI-ready, citing high-density power delivery, liquid cooling, and low-latency connectivity built for GPU clusters and AI training/inferencing workloads. This positioning spans specific expansion sites such as the Amsterdam (Haarlem) campus, which is being scaled toward 60 MW partly to serve hyperscale cloud and AI tenants, and the new Chennai, India campus being built out with an initial 23 MW at CHN-1 ahead of a planned 42 MW total. The company frames this as AI-ready colocation capacity layered onto its existing regulated-industry colocation business, rather than a separate AI-only product line.

Common Questions
Does Iron Mountain offer AI/GPU-ready colocation infrastructure?
Yes. Iron Mountain markets purpose-built AI-ready colocation with high-density power and liquid cooling for GPU clusters and AI inferencing/training workloads, and it positions several large campuses (e.g., Northern Virginia, Amsterdam, and its planned Chennai campus) as capacity for hyperscale cloud and AI customers, though this is offered alongside, not instead of, its traditional colocation product.
Does Iron Mountain operate underground data centers?
Yes. Its West Pennsylvania (WPA-1) facility near Boyers sits 220 feet below ground in a former limestone mine on a 200-acre campus, and its Kansas City facility (KCM-1) is also an underground site, both marketed for added physical security and natural energy efficiency.
How large is Iron Mountain's Northern Virginia data center campus?
The Manassas, Virginia campus spans 83 acres and is planned for up to four data center buildings totaling roughly 1,000,000 square feet, with the first two buildings (VA-1 and VA-2) already Uptime Institute Tier III certified.
How is Iron Mountain expanding in India?
Iron Mountain built its India presence through the Web Werks joint venture, with sites in Mumbai, Pune, Delhi-NCR, Hyderabad, and Bengaluru, and it is developing a new Chennai campus in the Ambattur area planned for 42 MW of power, with the first 23 MW (CHN-1) expected in 2026.
