One Communications is a Burlington, Massachusetts-based CLEC providing telecommunications services to commercial entities. The company was formally established on July 3, 2006, as the result of a merger between CTC Communications and Choice One Communications along with their acquisition of Conversent Communications.

On December 20, 2010, Earthlink (which has since been acquired by Windstream) announced that it would acquire One Communications for $370 million, which included payment of approximately $285 million of One Comm net debt. According to their press release, the acquisition will provide EarthLink with:

  • a strong IP network footprint in the Northeast, Midwest, and Mid Atlantic regions;
  • overlapping connection cities with EarthLink Business (formerly Deltacom & New Edge Networks) long-haul routes in major markets including Washington, D.C., Baltimore, Philadelphia and New York City;
  • geographical expansion and scale for managed IP services product strategy supported by a talented One Comm employee base; and
  • a solid foundation for potential future acquisitions of revenue bases in the region.

On April 1, 2011, Earthlink announced that it had completed the acquisition of One Communications. Following the close of the transaction, EarthLink planned to integrate One Comm into its "EarthLink Business" division.
