Zayo to Expand Atlanta Data Center Presence

Press Release

Four anchor tenants drive expansion to second facility

BOULDER, Colo. –
Zayo Group Holdings, Inc. (NYSE: ZAYO) will expand its Atlanta data
center presence with a new location at 1150 White Street SW. The
facility will add 72,100 total square feet and six megawatts (MW) of
critical power, and is the company’s second data center in Atlanta.

The expansion is driven by strong customer demand in Atlanta, including
commitments from four large companies in diverse sectors. The new
facility, expected to be fully operational in early 2018, will
complement Zayo’s facility located next door at 1100
White Street SW
. As a result of Zayo’s expansive fiber network,
which includes a fiber-to-the-tower
(FTT) build initiated in late 2015
, the company is experiencing
increased demand for both connectivity and colocation in the area.

Atlanta is a key gateway for global business, and has experienced
significant growth in technology, telecommunications, media, healthcare
and IT. The city is home to the third largest concentration of Fortune
500 companies.

“Atlanta is a vibrant and growing market, with a diverse base of
businesses contributing to strong demand,” said TJ Karklins, senior vice
president of Zayo’s zColo business segment. “This expansion furthers our
ability to serve the needs of enterprise and webscale customers with
Zayo’s high-quality colocation and high-scale fiber networks.”
