Next-generation Transportation Services Company Selects Zayo

Press Release

Wavelength solution includes diverse long haul and metro backhaul

BOULDER, Colo. –
A next-generation transportation services company has selected Zayo
Group Holdings (NYSE: ZAYO) for wavelengths to connect a new data center
in a major metropolitan area with its data centers on both coasts. The
solution includes diverse metro connectivity along with 100G long haul
wavelengths capacity.

The network will extend the provider’s network, supporting its core
business functions, corporate IT and research and development. The
routes are designed to provide geographic diversity and bypass existing
points of failure — providing resilient infrastructure with proximity
to the edge to better support their customer base.

Optical wavelengths provide dedicated, high-capacity bandwidth with
predictable low latency with no requirement for the customer to make a
large upfront capital investment to stand up their network

“Our solution, which includes diverse long haul and metro wavelengths
over unique assets, provided a significant advantage in winning this
business in a dynamic and rapidly expanding market,” said Randy Dunbar,
senior vice president, Transport. “The customer required a solution that
could scale to accommodate continued innovation and growth. Zayo is
well-positioned to provide them the solutions that meet their specific
needs — and more broadly, to meet the growing communications
infrastructure demand in this emerging sector.”
