What 123.Net does, and what this map holds
123NET is a Michigan fiber internet provider that also sells colocation and voice services and operates the Detroit and Grand Rapids internet exchanges. It also does colocation and data centers, DET-iX and GRR-iX internet exchanges, hosted voice, dark fiber and wavelengths, residential fiber. This map identifies 4 data centers operated by 123.Net across 1 state and 2 cities. Its largest presence is Michigan, with 4 buildings.
Disclosure is uneven and this page does not paper over it. 3 of the 4 publish a floor area, and 3 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 4 of these buildings, 89 network presences in total. That is a measure of how much traffic exchanges inside the building, not of its size.
