Zayo Group LLC

Formed in 2006 by two former Level 3 and ICG Communications executives, Zayo Group LLC consists of four business units; each operate autonomously with a core competency and focus on a specific area: bandwidth, fiber solutions, enterprise networks, and colocation. The umbrella operating company was formed when Zayo Bandwidth teamed up with two newly formed business units which were then called Zayo Managed Services and Onvoy Voice Services, a service provider of voice, data, and network services in Minnesota. Onvoy was spun off from Zayo Group during March 2010 and is now owned by Zayo Group Holdings, Inc.

Zayo Group LLC is headquartered in Louisville, CO and provides services over a fiber network that spans 150 markets in 30 states, 60 metro markets and nearly 21,000 route miles of fiber connecting over 3,300 buildings. The company maintains a growing network of customers primarily in the Northwest, Midwest and Mid-Atlantic by focusing efforts on underserved regional markets and linking them to larger metros.

Founded in November of 2006, Zayo Bandwidth is Zayo Group's premier fiber network operator providing bandwidth solutions to carriers, web-centric companies, public entities, educational institutions and enterprises. Its services include private line, wavelength, Ethernet, Internet and collocation. 

Zayo Fiber Solutions was born from the $73-million acquisition of AGL Networks, Atlanta. The Zayo segment focuses on dark fiber and custom network solutions and offers lit services like long-haul, local transport, private line, Ethernet, colocation, voice, and internet access.

Zayo Enterprise Networks, formerly called Zayo Managed Services, provides bandwidth infrastructure solutions to businesses, schools, hospitals, government agencies and regional telecommunications providers in markets across the United States. Key components include voice, videoconferencing, private data networks, webhosting, Internet and IT services. Zayo Enterprise Networks also allows customers to rent or purchase telecommunications equipment from five different partner companies including Cisco, Polycom, Tandberg, Linksys and Fortinet. The addition of this business segment in November of 2007 evolved Zayo from a fiber asset reseller to an actual service provider.

Zayo Colocation ( is a carrier neutral provider of colocation and interconnection services that was formed during 2009 after the FiberNet acquisition. This unit opened a new 9,000-square-foot data center in Nashville, TN during October 2010. Zayo Colocation also operates data centers in Chicago, Los Angeles, New York, and Newark, NJ.

Since May of 2007, Zayo Group has waged an aggressive expansion campaign. Since its inception, the Group has spent more than $400 million on acquisition investments. Most recently Zayo Group acquired American Fiber Network (AFN) in September 2010, AGL Networks (AGL) during July  2010, Citynet Fiber Network (CFN) in February of 2008, Northwest Telephone, Inc. (NTI) in June of 2008, and Columbia Fiber Solutions (CFS) in September of 2008. Zayo Group has strong financial backing from five experienced telecom and Internet investors: Battery Ventures, Columbia Capital, Centennial Ventures, MC Venture Partners, and Oak Investment Partners.
