Summary
Zayo Group
transit backbone fiber
Zayo is a large fibre and IP-transit provider (ZAYO-6461), best known for its
extensive metro and long-haul dark-fibre network across North America and
Europe.
What it's used for
- IP transit and wavelength/dark-fibre services to carriers, data centers, hyperscalers, and enterprises.
- Backbone and metro connectivity underpinning many other networks.
Notable
- Zayo is primarily an infrastructure (fibre/transport) provider; a lot of its value is the physical routes, with IP transit layered on top.
- Its rDNS encodes PoP/city codes, making Zayo routers useful path landmarks.
Interesting
- Zayo assembled its footprint through dozens of acquisitions of regional fibre operators during the 2010s.
