The source note identifies 4 MW as an expansion increment, not total facility capacity. The upstream row remains attributed below, but this value is not repeated as site capacity.

Provider notes
Energy. 123NET states DC1 is fed by a dedicated 20 MW DTE substation; the 20 MW figure is the utility feed, not measured IT load
Water. Operator states the expansion added both liquid-cooled and air-cooled infrastructure; the announcement does not describe the heat-rejection circuit, so the closed-loop-vs-evaporative question is unresolved.
What the source record says
Carrier-neutral colocation, home of the DET-iX Michigan internet exchange. Operator announcement dated 2025-09-24 (retrieved 2026-09-09) states a 4 MW expansion; that is the increment added, not a facility total, so capacityMw is omitted rather than recorded as 4. The announcement states liquid- and air-cooled capacity aimed at GPU clusters and AI inference, hence aiClassification mixed_use for a general-purpose colo that explicitly sells AI capacity. No investment, jobs, or incentive figures are stated. 123NET's own site lists further Southfield buildings (DC2, DC3); those were not confirmed against a fetched operator page in this run and are therefore not proposed here. Coordinates geocoded from the street address in the announcement; parcel not confirmed.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.

Sources and attribution
These sources are listed for the whole row. Unless a figure links to its own source, the provider does not mark which one gave it, so a figure may not appear in every source.
