Source-reported capacity; not metered consumption. Review underlying documents and notes. Planned capacity may include future phases and is not added to operational capacity here. The source may use facility, grid-feed or IT capacity definitions; consult the linked documents.
Coordinate precision is a source label, not an independent parcel survey. A marker does not confirm utility territory or establish an effect on residential bills.

No dated operational history is established in this record. Publication, discovery and source-update dates are not opening dates.
Source notes
123NET's only west-Michigan site. The operator's own facility list (retrieved 2026-09-09) states 3,500 sq ft at 400 76th St SW, Byron Center, while the operator's tech spec sheet (as of October 2026) states 4,300 sq ft of colocation space for Suite 12 at that address; the two operator figures differ, so no floor area is recorded. As of September 2026, the operator's facility list gives no per-facility MW figure; as of October 2026, the tech spec sheet lists 1 MW of available utility power, a utility feed rather than IT capacity, so no capacity is recorded. As of October 2026, the operator's tech spec sheet for this building lists the cooling type as direct expansion (DX), 150 tons, from 3 outside pad units with N+1 redundancy; direct-expansion cooling has no cooling water circuit, so it is recorded as air-cooled. US Signal's MI02 facility page gives the identical street address, so this address appears to be a shared multi-operator building rather than a single-operator site; the two are recorded as separate operator records. No investment, jobs, or incentive figures stated. Coordinates from the US Census geocoder; parcel not confirmed.
