Steadfast is a Chicago-based provider of colocation, dedicated server hosting, and cloud services that has operated since 1998, running its colocation footprint out of two of the Midwest’s most prominent carrier hotels in downtown Chicago plus a facility in the New York City metro area. As of 2026, Steadfast operates as a brand under ColoHouse, which acquired it in 2021/2022 along with its three data center locations: two suites in Chicago (350 E. Cermak and 725 S. Wells) and one inside the Iron Mountain building in Edison, New Jersey. Steadfast’s differentiator has historically been its deep, high-bandwidth interconnection between its own Chicago sites (over 400 Gbit/sec between 725 S. Wells and 350 Cermak) and its position inside 350 E. Cermak, once considered the world’s largest data center. The company sells colocation (cabinets, cages, and private suites) alongside public, private, and hybrid cloud hosting and managed/dedicated server products, making it a small-to-mid-sized regional operator rather than a national or hyperscale player.
Steadfast operates as a cloud provider and colocation provider, with facilities at the following locations:
