What CoreSite does, and what this map holds

Operates carrier-neutral colocation campuses where cross connects, peering exchanges and cloud on-ramps are the core product. It also does colocation (cabinets, private cages, private suites); owned by American Tower. This map identifies 34 data centers operated by CoreSite across 10 states and 16 cities. Its largest presence is California, with 13 buildings.

After California, CoreSite has the most data centers in Virginia (4), Colorado (3), Florida (3), Georgia (3), Illinois (2). 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. 26 of the 34 publish a floor area, and 2 publish a power figure. 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 28 of these buildings, 1,277 network presences in total. That is a measure of how much traffic exchanges inside the building, not of its size.

1 of these records is marked planned, permitted or under construction rather than operating, and each is labeled as such in the list below.

How big are CoreSite data centers?

They are not company-reported global totals, and this page never states a figure the record does not carry.
