Xspedius Communications
Xspedius Communications ("Xspedius") has been a pioneer in the telecommunications industry, both locally and nationwide. They are one of the few companies that can integrate landline telephone and Internet services for the business community. They have grown in size and innovation over the past several decades, from launching the
nation's first dial-up mobile phone service in 1958 and the introduction of an Integrated Service Platform in 1998 to a strategic acquisition in 2002, which significantly expanded the reach of their services.
Xspedius now has an operating footprint in 52 markets spanning 24 states, plus the District of Columbia, as well as more than 3,500 route miles of fiber.
