Zayo Expands European Wavelength Network

Press Release

Anchor customer selects Zayo for Marseille to Amsterdam solution

BOULDER, Colo. –
Zayo Group Holdings Inc. (NYSE: ZAYO) announced that it has completed a
coherent wavelength route from Marseille to Strasbourg via Milan. The
route, which also provides connectivity to Paris, Frankfurt, London and
Amsterdam, leverages Zayo’s European fiber network acquired from Viatel.

Initial customers include an India-based carrier, which selected Zayo
for a 100G wavelength solution on this route, with connectivity from
Marseille to Amsterdam. The solution will enable the carrier to extend
and harden its network into Europe, with diverse connectivity from these
two global gateway cities. Additional customers committed to this route
include a U.S.-based global Internet services provider and an
international wholesale telecommunications provider.

The route is part of Zayo’s expansion of its dark fiber and longhaul
wavelength network in Europe. Zayo now has several 100G and dark fiber
routes out of Marseille, a city that serves as a strategic gateway and
key aggregation point between Europe, Africa and Asia via subsea cables.

“With our expanded capability, we are well-positioned to meet the needs
of a growing base of global customers,” said Randy Dunbar, senior vice
president, Transport. “Our connectivity options in and out of Marseille
are opening up new international markets for us, and we continue to see
strong demand from multiple verticals.”

Customers can use Tranzact,
Zayo’s innovative shopping platform, to buy and manage network and
infrastructure solutions. The Tranzact platform enables customers to
access pricing, place orders, and view existing and pending services
