Overview
Iron Mountain Data Centers (IMDC) is the data-center business of Iron Mountain Incorporated, the US-listed records-management and information-storage company best known for storing physical documents and tapes for enterprises and government agencies. IMDC extends that information-storage franchise into digital infrastructure: it leases colocation space, power and interconnection to enterprises, cloud providers and hyperscalers, and develops larger build-to-suit and hyperscale campuses. The platform's distinctive asset base comes from Iron Mountain's legacy real estate. The company converted a number of its secure underground limestone-mine storage facilities — most famously its Western Pennsylvania site near Boyers — into hardened data-center space, and it also operates conventional above-ground data centers in major markets. Over time IMDC expanded through acquisitions and development in the United States, Europe and Asia-Pacific, including facilities in the London, Amsterdam, Frankfurt and Singapore markets, and it has marketed sustainability attributes such as renewable-energy procurement and power-usage effectiveness to large cloud tenants. Commercially, IMDC sits in the colocation and wholesale data-center segment, competing with specialist operators and real-estate-backed platforms. Its customers include enterprises seeking secure, compliant hosting for sensitive workloads as well as hyperscale cloud companies needing capacity. Because it is a segment of Iron Mountain rather than a separately listed company, its results are reported within the parent's global data-center business, and its strategy is closely tied to the parent's shift from paper records toward technology and asset-lifecycle services. For brand purposes, Iron Mountain Data Centers is a sub-brand of Iron Mountain: it borrows the parent's trust, security and compliance reputation while addressing a distinct buyer — the infrastructure and cloud procurement team rather than the records-management administrator.
History
Iron Mountain Data Centers grew out of Iron Mountain Incorporated's long history in physical records storage. Iron Mountain was founded in 1951 and built a business around secure storage of paper records, tapes and other media for enterprises, healthcare providers, law firms and government agencies. Its facilities were designed for security, redundancy and controlled access, and among its most unusual assets was a former limestone mine in Western Pennsylvania, near Boyers, used for deep underground records storage. As enterprise information shifted toward digital formats, Iron Mountain looked for ways to leverage its real estate, power infrastructure and security expertise. The underground facility in Pennsylvania, with its constant temperature, physical isolation and heavy security, was a natural candidate for conversion into data-center space, and the company began marketing hardened underground data-center capacity to customers with demanding security and continuity requirements. Iron Mountain formalized its data-center business as a distinct operating segment in the 2010s, and in 2017 it named the business Iron Mountain Data Centers, positioning it as a global platform for colocation and hyperscale leasing. The company expanded through acquisitions and development, adding capacity in the United States and entering major European markets including the London area, Amsterdam and Frankfurt, as well as Asia-Pacific through Singapore. These moves put IMDC in competition with established colocation providers and real-estate-backed data-center platforms. A central theme of IMDC's growth has been sustainability. Large cloud and enterprise tenants increasingly ask for renewable-energy sourcing, high power-usage effectiveness and transparent reporting, and Iron Mountain has marketed its data-center portfolio on those attributes, including renewable-energy procurement and green-building certifications at various sites. The business also emphasizes interconnection and network density in its major-market campuses so that customers can connect to cloud on-ramps and carriers. IMDC operates as a segment of Iron Mountain Incorporated rather than as a standalone public company, so its financial results are reported within the parent's overall business. Its trajectory reflects the parent company's broader strategic shift from paper-based records management toward technology, digital infrastructure and asset-lifecycle services, while still drawing on the trust and security reputation built in the records-storage era.

Nine PBS sues Iron Mountain Data Centers over access to 50TB archive[3]
Nine PBS, the public television station in St. Louis, sued Iron Mountain Data Centers in Denver District Court seeking the return of roughly 50 terabytes of archival material held in a Denver facility after its cloud storage provider Open Source Storage went defunct and cut off access. A Denver judge ruled that Nine PBS owns the material and ordered Iron Mountain to cooperate on retrieval within 30 days. Iron Mountain says it never had access to the data, arguing it rents physical space to OSS and that handing over a third party's hardware would have breached its contracts and exposed other clients' data.
