Zayo, the leading digital network infrastructure provider, ranks No. 6 on Vertical Systems Group’s Mid-2026 U.S. Carrier Ethernet LEADERBOARD, moving up from the Challenge Tier after acquiring Crown Castle’s Fiber Solutions business, the deal Vertical Systems Group cited for the move.

What is the U.S. Carrier Ethernet LEADERBOARD?

The LEADERBOARD is Vertical Systems Group’s ranking of U.S. Carrier Ethernet providers based on retail port share as of June 30, 2026. Providers are required to have 4% or more of the U.S. retail Ethernet services market to qualify for the LEADERBOARD, while providers with between 1% and 4% market share are included in the Challenge Tier.

How did Zayo move up to No. 6?

Zayo closed its acquisition of Crown Castle’s Fiber Solutions business in May 2026, expanding Zayo’s metro footprint and enterprise reach across the U.S.

“AI and cloud growth depend on the networks that connect them,” said Sowmyanarayan Sampath, CEO of Zayo. “Our move onto the LEADERBOARD reflects the scale of Zayo’s digital infrastructure assets and our ability to put capacity where demand is today and where it’s headed in the future.”

What did the Crown Castle Fiber Solutions deal add to Zayo?

Crown Castle’s Fiber Solutions business added approximately 90,000 metro route miles and approximately 40,000 on-net enterprise locations to the Zayo network. The combined network spans 32 million fiber miles and 224,000 route miles across North America, expanding Zayo’s metro reach and density alongside its extensive long-haul network.

Seven providers qualified for the Mid-2026 LEADERBOARD with at least 4% of the U.S. retail Ethernet services market.
