Global Webscale Company Selects Zayo for Long Haul Dark Fibre

Customer commits to recently announced Reno to Umatilla, Oregon route

BOULDER, Colo. – March 16, 2018 – A global webscale customer has selected Zayo Group Holdings, Inc. (NYSE: ZAYO) for dark fibre services on its Reno to Umatilla route, which is currently under development. The deal further supports Zayo’s investment in this route as a follow-on to the initial anchor customer sale announced earlier this year.

The high-fibre count network will provide additional diversity to the customer’s data centres in the Northwest. Increasingly, webscale companies are moving to triversity or quadversity to ensure fully resilient networks.

The new route is adding more than 600 route miles connecting Umatilla, Oregon, with Reno, Nevada, a fast-growing data centrehub. The fully underground route creates a diverse route between Portland and other major cities on the west coast. The route will also be available for 100G wavelengths in addition to dark fibre once completed.

“In addition to this follow-on customer sale, this strategic route has generated a funnel of other sales opportunities,” said Jack Waters, CTO and president of Fibre Solutions at Zayo. “As more companies add data centres in Oregon and Nevada, Zayo is well positioned to provide high-capacity fibre infrastructure.”
