NTT data centers
Listed below are 26 data centers operated by NTT in the United States, identified from primary sources across 7 states and 10 cities.
What NTT does, and what this map holds
Japanese telecom group's data center arm; operates seven US multi-tenant campuses selling cabinets, cages, private suites, powered shell and build-to-suit capacity. It also does retail colocation (cabinets, cages, suites), carrier-neutral data center connectivity, IT and cloud services, global IP network. This map identifies 26 data centers operated by NTT across 7 states and 10 cities. Its largest presence is Virginia, with 13 buildings.
After Virginia, NTT has the most data centers in California (5), Illinois (3), Texas (2), Arizona (1), Oregon (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. 20 of the 26 publish a floor area, and 15 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 10 of these buildings, 68 network presences in total. That is a measure of how much traffic exchanges inside the building, not of its size.
7 of these records are marked planned, permitted or under construction rather than operating, and each is labeled as such in the list below.

They are grouped below by state and then by city. NTT's largest presence is Virginia with 13 buildings, followed by California (5), Illinois (3), Texas (2), Arizona (1).
How big are NTT data centers?
20 of the 26 publish a floor area and 15 publish a power figure. Both are shown against the individual building rather than summed, because a floor area for one hall and an announced campus capacity are not the same measurement.
