WEBSCALE CLOUD PROVIDER SELECTS ZAYO FOR METRO DARK FIBER

Solution leverages dense metro fiber in Chicago

BOULDER, Colo. – February 21, 2017 – A global webscale cloud provider has selected Zayo Group Holdings, Inc. (NYSE: ZAYO) for metro dark fiber in Chicago. The project will connect six data center locations with 20 diverse segments totaling 280 strands across all segments, with up to 26 strands per segment. The solution is built on Zayo’s dense metro network in Chicago, with more than 90 percent of the solution leveraging in-place network.

Demand for cloud services continues to grow, with experts predicting that organizations will continue to shift their IT workloads and infrastructure to off-premise data centers. Approximately 60 percent of that infrastructure will operate in the cloud, according to a recent IDG Cloud Computing Survey. To make this distributed architecture work, cloud providers and customers both rely on high-bandwidth connectivity to transport workloads rapidly, reliably and securely.

“Zayo is well positioned to meet the needs of global cloud providers for connectivity, both within their enterprise and to business customers,” said Joe Stockhausen, vice president, Dark Fiber Solutions, Central Region at Zayo. “Our fiber density, network diversity and ability to meet aggressive delivery requirements were differentiators that won us this deal.”
