Overview
360networks was a Canadian-based wholesale telecommunications carrier focused on building and operating long-haul fiber-optic infrastructure. Its network strategy centered on connecting major North American markets through both dark fiber, which customers could light and operate themselves, and lit fiber services supplied with transmission capacity. Several of its routes followed railway rights of way, an approach that helped address one of the principal practical constraints on large-scale fiber deployment: securing corridors for cable construction. The business began as Pacific Fiber Link, L.L.C. in 1998 as a subsidiary of Ledcor Industries of Canada, part of the Ledcor Group of Companies. Its initial project focused on a fiber route between Seattle and Sacramento. The company subsequently negotiated access to Canadian National Railway rights of way and developed a specialized construction method known as the Railplow. Mounted on a railcar, the system was designed to excavate a narrow trench alongside railway tracks, install conduit for fiber-optic cable, and restore the corridor rapidly. A related patent was held by a subsidiary, while 360networks received a royalty-free exclusive license to use the technology. The company changed its name to Worldwide Fiber Networks, Inc. in 1999 as it broadened its ambitions beyond the initial route. In 2000 it adopted the 360networks name, reflecting management's stated intention to develop a globally oriented network. During the telecommunications and internet infrastructure boom, it attracted investments associated with Michael Dell, Nathan Myhrvold, Liberty Media, and News Corp. It also appointed Greg Maffei, formerly chief financial officer of Microsoft, as chief executive officer. The company went public in January 2000 and used acquisitions and construction programs to expand its infrastructure position. Expansion included the purchase of substantial equipment and networking space in Los Angeles, Atlanta, and Dallas, as well as the acquisition of approximately 11,000 miles of fiber-optic infrastructure from Call-Net Enterprises. The company also pursued international development and received a license in 2001 to own infrastructure in Japan. Its growth, however, took place amid a sharp reversal in telecommunications-market conditions. The company skipped a debt payment in early June 2001 and filed for bankruptcy protection in Canada and the United States on June 28, 2001. 360networks emerged from bankruptcy in November 2002. Its post-bankruptcy period included the acquisition of Group Telecom, the purchase of Dynegy's U.S. communications business, the acquisition of Touch America's assets out of bankruptcy, and the sale of selected assets to Qwest. In 2004 it sold its Canadian assets to Bell Canada for C$275 million. Greg Maffei left the chief executive role in 2005 to join Oracle Corporation but remained chairman for a period. The company ultimately ceased to exist as an independent carrier when Zayo Group acquired it in December 2011. Its principal legacy was a portfolio of long-haul fiber routes and related network assets integrated into a successor operator rather than a continuing standalone consumer brand.
History
360networks was established as Pacific Fiber Link, L.L.C. on February 5, 1998, by Ledcor Industries of Canada, a company within the Ledcor Group of Companies. It began business operations on May 31, 1998. The initial plan was to construct a fiber-optic route linking Seattle and Sacramento, but the company soon developed a broader North American strategy. A central operational problem for the telecommunications industry was obtaining rights of way for new fiber routes. 360networks addressed this by negotiating with Canadian National Railway to install cable alongside railway tracks. The railway-corridor model gave the company access to long linear routes while reducing the need to acquire separate parcels of land. It also supported the development of the Railplow, a rail-mounted construction system capable of excavating, installing conduit, and backfilling in a relatively rapid sequence. The Railplow patent was transferred to a subsidiary of the relevant companies, and 360networks received a royalty-free exclusive license to use the system. In 1999 the business became Worldwide Fiber Networks, Inc., reflecting its move toward a larger network concept. In 2000 it became 360networks Inc., while its American operating entity was named 360networks (USA) Inc. The company recruited Greg Maffei, formerly Microsoft's chief financial officer, as chief executive officer. It also obtained private-equity support associated with Michael Dell, Nathan Myhrvold, Liberty Media, and News Corp. The company undertook an initial public offering on January 2, 2000, at the height of the telecommunications infrastructure boom. The expansion program combined internal construction with acquisitions. In May 2000, 360networks acquired about one million square feet of space in Los Angeles, Atlanta, and Dallas for network equipment. In August it acquired approximately 11,000 miles of fiber-optic infrastructure from Call-Net Enterprises for $162.5 million. The company continued international development and received a license in May 2001 to own infrastructure in Japan. Its network included long-haul routes such as Chicago–New Orleans, Chicago–Denver, Chicago–Detroit, Chicago–New York, Seattle–Los Angeles, and Denver–San Francisco. These routes included dark and lit fiber capacity. The sector's downturn exposed the company's financial vulnerability. 360networks missed a debt payment in early June 2001 and filed for bankruptcy protection in both Canada and the United States on June 28. WL Ross & Co acquired a 12.5 percent interest in October 2002, and the company emerged from bankruptcy the following month. The restructured business acquired Group Telecom in November 2002, bought the U.S. communications business of Dynegy in May 2003, and sold assets to Qwest in November 2003. In January 2004 it acquired the assets of Touch America out of bankruptcy, while in May it sold its Canadian assets to Bell Canada for C$275 million. Maffei left the chief executive position in July 2005 to work for Oracle Corporation, although he remained chairman. The company's independent corporate life ended in December 2011, when Zayo Group acquired it. 360networks is therefore best understood as a historical wholesale network operator whose infrastructure and operations were absorbed into a later telecommunications platform.

Products and positioning
Wholesale telecommunications infrastructure provider specializing in long-haul fiber-optic routes and carrier-grade network connectivity.
North American long-haul fiber networkTelecom infrastructure1998
360networks developed long-distance fiber-optic routes across Canada and the United States, including connections among Chicago, New Orleans, Denver, Detroit, New York, Seattle, Los Angeles, and San Francisco. The network used railway rights of way for many routes and supported wholesale carrier connectivity.
Dark fiber servicesWholesale network service
The company provided access to unlit optical fiber, allowing wholesale customers and other network operators to install and manage their own transmission equipment. Dark fiber formed part of the long-haul infrastructure portfolio later absorbed through corporate and asset transactions.
Lit fiber servicesWholesale network service
360networks also operated lit fiber capacity, meaning transmission infrastructure supplied with active optical equipment and usable network capacity. These services supported carrier-grade, long-distance telecommunications connections rather than consumer retail communications.
Railplow construction technologyFiber deployment technology
The Railplow was a rail-mounted construction system used to excavate alongside railway tracks, install conduits for fiber cables, and restore the trench. 360networks held an exclusive royalty-free license to use the patented technology, which supported rapid deployment along railroad corridors.
