With 450,000 route miles of fiber, Lumen Technologies is one of the United States' largest telecommunications carriers serving global enterprises. Its merger with Level 3 in 2017 and divestiture of much of its incumbent local exchange carrier, or ILEC, business in 2022 have shifted the company's operations away from its legacy consumer business and toward enterprises (now about 75% of revenue). Lumen offers businesses a full menu of communications services, providing colocation and data center services, data transportation, and end-user phone and internet service. On the consumer side, Lumen has announced the sale of its consumer fiber network, but will maintain and harvest its legacy consumer copper network.
