Global Technology Company Selects Zayo for Dark Fiber

Press Release

Solution leverages Zayo’s dense fiber network in Chicago

BOULDER, Colo. –
Zayo Group Holdings, Inc. (NYSE: ZAYO) has been selected by a global
technology company for metro dark fiber in Chicago. The solution will
provide additional high-performance capacity between the company’s data
centers.

The solution leverages Zayo’s
dense Chicago fiber network
that spans more than 1,600 route miles
and connects more than 35 data centers. Dark fiber offers substantial
levels of bandwidth, a higher level of control and long-term lease terms.

Chicago is a key market and hub for Zayo, with a high-count fiber
footprint, providing customers with unique routes to meet capacity and
diversity needs. Zayo operates four
zColo data centers in the metro area
, with a total footprint of more
than 258,000 critical square feet.

Zayo also provides diverse connectivity into 350 Cermak, one of the
world’s largest data centers. 350 Cermak is a key carrier hotel in the
region and a backbone of the internet. Chicago is one of the top data
center markets in the U.S. due to affordability of power, available
fiber connectivity and low exposure to natural disasters.

In addition to Zayo’s Chicago metro fiber footprint, Zayo has several
major long haul routes that connect into the city, including New
York/New Jersey to Chicago via the low-latency Spread
Networks by Zayo route
, Columbus to Chicago, Minneapolis to Chicago,
Omaha to Chicago, Indianapolis to Chicago, St. Louis to Chicago and
Toronto to Chicago.

“Zayo’s high fiber count footprint in Chicago enables us to be one of
the few providers that can offer customers diverse dark fiber along with
access to long haul routes,” said Steve Orlando, senior vice president
of Central Region at Zayo. “In this case, our customer continues to
require additional bandwidth to accommodate growth, and we look forward
to increasing their dark fiber capacity.”
