In the U.S., XO owns and operates one of the largest IP and Ethernet networks that customers rely on for private data networking, cloud connectivity, unified communications and voice, Internet access, and managed services.

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.  XO also has added direct fiber-connected buildings onto its network and now has nearly 5,000 On-Net buildings. 

XO holds an extensive list of accolades including the “2016 Unified Communications Product of the Year Award” for XO Hosted PBX service and the “2015 Infotech Data Center Excellence Award” for XO Bandwidth on Demand service, both given by TMC.  Additional recognition includes being placed on the “InformationWeek List of 500 Top Technology Innovators” in 2013 for service delivery automation and receiving the “2012 Leading Lights Award – Best New Telecom Service” for 100 Gbps service by Light Reading.
