Zayo data centers
Listed below are 7 data centers operated by Zayo in the United States, identified from primary sources across 7 states and 7 cities.
What Zayo does, and what this map holds
Fiber network operator selling transport, wavelengths, dark fiber, IP and managed connectivity over 240,000+ route miles. It also does colocation at network sites, managed security, UCaaS. This map identifies 7 data centers operated by Zayo across 7 states and 7 cities. Its largest presence is Colorado, with 1 building.
After Colorado, Zayo has the most data centers in Maryland (1), Minnesota (1), Ohio (1), Pennsylvania (1), Tennessee (1). Each state below links to that state's own page, which carries every operator in it, the grid operator, and the moratorium, water and delay record that applies there.
Disclosure is uneven and this page does not paper over it. 1 of the 7 publish a floor area. Each figure is shown against the building it belongs to and never added into a single total, because operators do not measure the same thing: one states the floor area of one hall, another the full capacity of a campus it has only announced.
PeeringDB records networks meeting in 6 of these buildings, 20 network presences in total. That is a measure of how much traffic exchanges inside the building, not of its size.
