Zayo

Zayo sells bandwidth infrastructure: high capacity dedicated internet, Ethernet, wavelength services, and dark fiber on a network spanning major metro and long haul routes across North America and Europe, with deep reach into data centers and carrier hotels. It is not an internet provider for an office that needs a connection; it is the provider businesses graduate to when connectivity becomes infrastructure, when the requirement reads in tens or hundreds of gigabits, when latency between specific facilities matters, or when the right answer is owning lit or dark capacity rather than renting a circuit. Its data center connectivity is a particular strength, linking enterprise sites to the colocation and cloud on ramp facilities where modern architectures actually terminate. Pricing is entirely quote based and depends on route, building status, and term, with on net buildings dramatically cheaper and faster to serve than anything requiring construction. The honest scope note: a single location business or a standard multi site WAN has no reason to start here, and Zayo's sales motion is built for infrastructure buyers, not small accounts. For bandwidth intensive businesses, media, research, AI workloads, financial services, multi site data movement, Zayo belongs on the shortlist and prices sharpest when compared against the other fiber infrastructure players on the same route.
