International Carrier Selects Zayo for Dark Fiber in Europe

Solution provides capacity, latency benefits

BOULDER, Colo.–(BUSINESS WIRE)–An international carrier has selected Zayo Group Holdings, Inc. (NYSE:
ZAYO) for a pan-European dark fiber backbone. The dark fiber solution
includes a nearly 3,500 route-mile network with dozens of ILA stations,
connecting four major European markets. It leverages Zayo’s in-place
network in the U.K. and Western Europe. The solution supports the
carrier’s European expansion, providing capacity and latency advantages.

The carrier connects to Zayo’s network via subsea cables in Marseille, a
strategic gateway and intercontinental aggregation point. Zayo provides
diverse fiber routes from Marseille that connect to Paris, Frankfurt,
London and other European markets. Zayo announced
last year
that the company offers three fully diverse network routes
out of Marseille, facilitating resilient fiber options across Western
Europe.

“Zayo has a growing track record of helping carriers expand globally,”
said Annette Murphy, managing director, Zayo Europe. “This is a
significant win, which we were awarded because of our high level of
service and the strength of our European network footprint, which
enables the carrier to connect and expand to all major markets.”
