What FirstLight does, and what this map holds

Northeast fiber network operator selling internet, Ethernet, wavelengths, dark fiber and voice, with colocation and cloud as secondary services. It also does colocation and cloud (Cloud & Data Center services), managed services, unified communications, security. This map identifies 32 data centers operated by FirstLight across 5 states and 16 cities. Its largest presence is New Hampshire, with 12 buildings.

After New Hampshire, FirstLight has the most data centers in Maine (7), Massachusetts (7), New York (4), Vermont (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. 10 of the 32 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 4 of these buildings, 5 network presences in total. That is a measure of how much traffic exchanges inside the building, not of its size.

Counts are what primary sources describe in the United States as of 2026-09-02: the operator's own published facility list, PeeringDB, OpenStreetMap, Wikidata, and county and state building registers.
