Zayo Announces Significant Expansion to IP Transit Capacity in Key Metro Markets

Press Release

Increased demand on critical communication infrastructure continues across US

BOULDER, Colo. –
Zayo Group Holdings, Inc. today announced a significant expansion to its IP Transit capacity in key metro markets across the United States. Based on increased demand to 100G ports, Zayo recently completed upgrades to support 100G IP Transit in Phoenix, San Jose and Denver. These three metro areas join Atlanta, Boston, New York, Miami, San Francisco and Seattle in benefiting from Zayo’s 100G enabled services.

The demand for increased capacity continues to grow across multiple sectors, with the number of networked devices and connections in North America alone expected to increase from 3 billion in 2018 to 5 billion in 2023. To meet demand, Zayo is ramping-up its investment in capacity to support remote working, remote education, telehealth, business critical applications, and an overall global increase in public IP traffic.

These ongoing investments enabled Zayo to seamlessly support the significant surge in requests for bandwidth during the early stages of the pandemic, a result of businesses and organizations transitioning to mass home working effectively overnight. Julia Robin, Senior Vice President, Layer 3 Services, said: “We’re also meeting requests from higher bandwidth consumers as they work to support the major increase in traffic on their own platforms. In many cases, the requests are for significant increases in bandwidth, even doubling capacity.”

The overall trend in demand on networks, including the need for capacity, diversity and low latency, is expected to continue due to the rapid adoption of 5G, next generation satellite networks, genomics, telemedicine and more.
