Large Cloud Provider Selects Zayo for Wavelength Connectivity

Press Release

|14 February 2018

Solution provides high-capacity triversity between large data centres

BOULDER, Colo. –
A global webscale cloud provider has selected Zayo Group Holdings, Inc.
(NYSE: ZAYO) for wavelength connectivity. Zayo’s solution will provide
high-capacity connectivity between a major west coast data centre and
another facility located centrally in the U.S.

The solution will provide the customer with triversity between the data
centers, with up to 2TB of capacity. The customer selected Zayo for its
ability to provide a completely separate, high-capacity route to
complement its primary and secondary networks. Increasingly, cloud
providers require diversity at a minimum and are moving more towards
triversity or quadversity to ensure fully reliable redundancy.

The global public cloud market is expected to grow approximately 35
percent over the next two years, according to a recent
report
from Gartner. To handle the demand, providers are investing
to expand and bullet proof their infrastructure, which includes
redundant fibre and lit fibre-based connectivity between data centres.

“We were able to secure this contract because of our existing fibre
infrastructure, lit fibre-based footprint and ability to mobilize to
complete the project very quickly,” said Andrew Crouch, president and
COO at Zayo. “Earning this business is an important vote of confidence
from a long-standing customer.”
