Data Center IT Asset Recovery in Chicago, IL
30 verified data center facilities in Chicago, IL, operated by 22 companies, run servers, storage arrays, switches, routers, and power infrastructure on continuous refresh cycles. Every hardware refresh, consolidation, and full-site decommission across these facilities produces a stream of retired IT assets, and the disposition path chosen for that equipment determines both the data-security exposure it carries and the value that can be recovered from it. ITAMG buys decommissioned IT equipment from Chicago data center operators, colocation tenants, and enterprises, pairing secure on-site data destruction with remarketing so that retired hardware leaves the building fully documented, sanitized, and credited back against its residual value rather than written off as waste.

How ITAMG Verifies Chicago, IL Data Center Data
Every facility on this page has been compiled from the directory's 15 source datasets, including operator filings, regulatory disclosures, and industry databases, and cross-checked where more than one source reports it. ITAMG matches records by name, address, geographic coordinates, and operator identity, then collapses duplicates into a single canonical entry. Where a facility hosts multiple providers, the Index reports the facility operator, which may differ from a provider named in the facility's name. A facility appears here only when two conditions hold. First, the building must be locatable on a map by either coordinates or a verified street address. Second, the record must describe an actual data center, not a colocation reseller, a telco hub, or a paper-only mention in a financial filing. Records that fail either test are excluded.
