Zayo review & pricing
Our verdict
The infrastructure-grade pick: when a business needs serious fiber (dedicated internet at 10G+, wavelength, dark fiber or carrier diversity), Zayo is usually on the shortlist. Buyer experience is telecom-traditional — quotes move through channel partners and larger deals take engineering time.
Overview
Zayo is one of North America's largest fiber network owners, with 17M+ fiber miles serving carriers, enterprises and hyperscalers — dark fiber, wavelengths, lit services and (since the Crown Castle acquisition) an expanded small-cell estate.
Best for
- Enterprises needing high-capacity dedicated internet or wavelengths
- Multi-site organizations wanting fiber diversity/redundancy
- Carriers and data centers buying transport or dark fiber
Pros & cons
What we like
- Massive national long-haul and metro fiber footprint
- [object Object]
- Strong enterprise SLAs with jitter/latency commitments
- Post-Crown Castle acquisition, stronger in-building/dense-urban reach
What to watch
- Traditional telecom sales cycles; not built for tiny offices
- On-net buildings great, off-net construction costly and slow
- Support better at enterprise tiers than SMB
