Zayo Announces 400Gbps Upgrade and Significant Network Expansion

Representing an investment totaling nearly a quarter of a billion dollars, Zayo is currently expanding its global network backbone significantly. In addition, the company expects to have largely upgraded its backbone to 400Gbps by the end of 2022.

Zayo’s key new dark fiber routes include: Cleveland-Columbus, Dallas- Atlanta, Denver- Salt Lake City, and Las Vegas- Phoenix. Zayo will continue to yield new and upgraded routes globally over the next 18 months.

“Enterprises of all sizes are entering a transformational, yet highly-complex time as they face a convergence of factors ranging from digital-first implementation and the future of work to rapid cloudification and edge computing,” said Andrés Irlando, President at Zayo.

“Enterprises of all sizes are entering a transformational, yet highly-complex time as they face a convergence of factors ranging from digital-first implementation and the future of work to rapid cloudification and edge computing,” said Andrés Irlando, President at Zayo. “At Zayo, we recognize that each of these advancements is only as successful as the connectivity empowering it. We are committed to continuous expansion and advancing our network and capabilities, and we remain focused on exceeding customer expectations now while positioning them for a future they are just now imagining.”

“Cogent Communications is at the cutting edge of the IP / communications industry, and we are constantly expanding our footprint to new facilities and new markets,” said Dave Schaeffer, CEO of Cogent Communications and a Zayo customer. “Zayo’s future-ready, reliable dark fiber network with route diversity is an essential component in our network design to deliver best-in-class, scalable, and reliable IP services that our customers have come to expect from Cogent. We look forward to leveraging Zayo’s dark fiber footprint to grow our network in the future.”

5G, Cloud, IoT, AI, Edge Computing

Nearly half of Zayo’s 75,000-mile backbone network is already 400G capable, with the majority of the network expected to be finished by the end of 2022.

As a result of this network upgrade, clients would be able to keep growing as they implement new technologies like 5G, cloud adoption, IoT, AI, edge computing, and automation thanks to this increased capacity. Zayo has conducted a successful subsea 400G experiment with Equinix in the United Kingdom, assisting the data center operator in preparing for the rising demand to transmit larger amounts of data quicker than ever before.

Zayo’s key new 400G routes include the following:

  • Dallas – Atlanta (creating the company’s third major East-West route)
  • Chicago – New York
  • Denver – Chicago
  • Denver – Salt Lake City (which completed the shortest route from San Francisco to New York, via Chicago)
  • Los Angeles – Phoenix- Dallas
  • Salt Lake City – San Francisco Bay Area
  • San Francisco Bay Area – Los Angeles

Zayo is quickly differentiating itself as a market leader when it comes to network diversity, capacity and future-readiness,” said Will Townsend, Vice President & Principal Analyst, Networking & Security at Moor Insights & Strategy. “A proof point is its new coast-to-coast route that traverses nearly a straight line across the U.S., delivering 400G performance that supports low-latency-intensive applications such as financial trading. Zayo’s recent network build-outs represent an investment in future capacity for its customers.”
