The company, initially named NEXTLINK, first launched voice communications services on July 4, 1996. In the wake of the Telecommunications Act of 1996 , NEXTLINK was one of the first Competitive Local Exchange Carriers (CLECs) in the United States. Its core operations office was located in Bellevue, Wash., and the company at that time served seven markets in three states.

During the late 1990s, the company rapidly expanded into major markets across the United States, and became the largest LMDS license holder in the country through the historic FCC spectrum auction in 1998. In 2000, NEXTLINK acquired Concentric Network Corporation, the nation’s third largest independent Internet service provider. The combined company was renamed XO Communications to signify its transformation into a full-service, integrated broadband communications provider. That same year, XO established its headquarters in Northern Virginia. Today, XO offers comprehensive data networking, cloud connectivity, unified communications, voice, Internet and managed services to businesses in 85 markets across the United States.

In addition to the 85 markets served in the United States, XO extends service to more than 50 countries via a variety of partners through points of presence in Amsterdam, Frankfurt, Hong Kong, London and Toronto. The company has 1.5 million fiber strand miles in its network, including approximately 20,000 route-miles of intercity and 13,500 route-miles of metro fiber.
