US Signal is a Midwest-rooted colocation and cloud provider that, as of 2026, operates 17 data centers across nine U.S. states, all tied together by its own privately owned fiber network spanning thousands of route miles. Founded in 2001 in Grand Rapids, Michigan (originally as US Xchange), the company built its footprint organically in secondary Midwest markets — Grand Rapids, Detroit, Chicago, Indianapolis, South Bend, and Madison — before expanding into Denver, Phoenix, Bend (Oregon), Des Moines, and Minneapolis/St. Paul through a wave of acquisitions, most notably the 2024 purchase of TDS’s OneNeck Data Center Holdings (adding six data centers across Arizona, Colorado, Iowa, Minnesota, Oregon and Wisconsin) and a 2023 Indianapolis acquisition. In 2026 it further expanded with a new Aurora, Illinois facility. Backed by infrastructure investor Igneo Infrastructure Partners, US Signal has pursued a stated strategy of building a distributed, edge-focused national platform, and announced a $200 million capital-expenditure program in mid-2025 to add power-dense capacity — including AI-oriented upgrades — at several of its sites, notably Detroit and Des Moines.

Common Questions
How many data centers does US Signal operate, and where?
As of 2026, US Signal's own site lists 17 data centers across Michigan (five, including Grand Rapids and three around Detroit), Illinois (Oak Brook and Aurora), Indiana (two in Indianapolis, one in South Bend), Wisconsin (two in Madison/Fitchburg), Iowa (Des Moines), Minnesota (Minneapolis/St. Paul), Arizona (Phoenix/Gilbert), Colorado (Denver/Englewood), and Oregon (Bend).
Does US Signal offer AI/GPU-ready infrastructure?
US Signal has been adding AI-oriented, high-density capacity at specific sites: its MI03 Detroit-area (Belleville) facility was recently expanded to support growing AI and edge computing workloads, and its Des Moines (IA01) facility is receiving 6 megawatts of new commercial power to support high-density, next-generation AI, cloud, and edge workloads as part of a $200 million company-wide capital program announced in 2025.
How did US Signal grow from a regional Midwest provider to a multi-state operator?
The company expanded significantly through acquisitions, most notably buying TDS's OneNeck Data Center Holdings in 2024 (adding data centers in Arizona, Colorado, Iowa, Minnesota, Oregon, and Wisconsin), acquiring a second Indianapolis facility in 2023, and acquiring a new Aurora, Illinois facility in early 2026.
Is US Signal a colocation company or a cloud provider?
Both — US Signal sells physical colocation space (cages, cabinets, and cageless rack space) for customers' own equipment across its data centers, and it also sells its own private/multi-tenant cloud platform, branded OpenCloud, delivered from within its facilities.
