123NET, a privately owned telecommunications company founded in 1995 and headquartered in the United States (Michigan), employs approximately 270 people. The company primarily provides data center, network, and voice services to businesses.
123NET hosts the Detroit Internet Exchange (DET-iX), a nonprofit, carrier-neutral, fee-free Internet Exchange Point located in Southfield, Michigan. In December 2023, the Ottawa County Board of Commissioners approved a $15 million project for 123NET to install 325 miles of new fiber lines, bringing high-speed internet access to the county. By August 25, 2025, 123NET connected its first customers in Ottawa County as part of this project, providing high-performance internet access to approximately 2500 underserved businesses and residents. This fiber installation will connect to 123NET's existing 4000-mile Michigan network, which links to multiple data centers and peering exchanges.
