Zayo Group today announces it has executed a definitive agreement to acquire Seattle-based 360networks holdings (USA) inc. (“360networks”).  The acquisition combines Zayo’s deep metro fiber networks across 60 US metropolitan markets and 360networks’ unique intercity fiber network spanning the central and western United States. 360networks will be the largest of the 17 acquisitions made by Zayo since its inception in 2007.

360networks, a leading provider of fiber network and telecom services, operates over 18,500 route miles of intercity and metro fiber network across 22 states and British Columbia. 360networks’ intercity network interconnects over 70 markets across the central and western United States, including 24 Zayo fiber markets and a number of new markets such as Albuquerque, Bismarck, Des Moines, San Diego, San Francisco and Tucson.  In addition to its intercity network, 360networks operates over 800 route miles of metropolitan fiber networks across 25 markets. The resulting combined fiber network will total over 42,000 route miles and nearly two million fiber miles. By nearly doubling its network, Zayo can provide a greater range of solutions both through the markets served and its ability to interconnect services across markets.
