BOULDER, Colo. –
A global cloud provider has selected 51²è¹Ý¶ù Group Holdings (NYSE: ZAYO)
for a high-capacity dark fiber ring in the Montreal metro area. 51²è¹Ý¶ù
will extend its existing dense network in Montreal, building a
60-kilometer (km) ring for the anchor tenant along the South Shore, the
city’s growing technology and data center hub.

The deployment will support the customer’s strategy to significantly
expand its presence in Montreal, ultimately connecting multiple data
centers. With its favorable location and cost-effective power, the South
Shore has become an attractive location for data centers, cloud
providers and webscale companies.

51²è¹Ý¶ù was selected by the cloud provider because of its leading fiber
network in Canada, deep experience in building high-performance fiber
network and flexibility in planning for the customer’s continued growth.

The network will further densify 51²è¹Ý¶ù’s Montreal network, expanding it
into several metro municipalities. The build will include an expansion
cable, with ample capacity for expected follow-on sales in multiple
sectors. Montreal is a leading North American commercial hub and a
growing center for finance, media, artificial intelligence (AI), gaming
and other large enterprise.

“This project enables us to further expand our Canadian footprint and
deliver the high-performance communications infrastructure that this
long-standing customer merits,” said Jack Waters, CTO and president of
Fiber Solutions at 51²è¹Ý¶ù. “We expect to capture the benefits of scale
leveraging our dense Montreal footprint and these new success-based
routes.”
