The record, newest first
CyrusOne's Norwalk web page lists 4 MW of total IT capacity and power feeds from two utilities. (CyrusOne, Oct. 27, 2026)

Conflicts and open questions
- CyrusOne's own figures differ: its web page introduction cites a 150,000 sq ft facility, while the facility sheet and the page's feature list give 168,000 sq ft.
- The 16 MW figure on the facility sheet is backup power capacity; the 4 MW figure on the web page is IT capacity.
The full record
- Status note
- CyrusOne's location page describes the Norwalk facility in the present tense and does not label it as in development (checked October 2026).
- Power note
- 4 MW is the total IT capacity on CyrusOne's web page; total facility load was not stated. The facility sheet separately lists up to 16 MW of redundant backup power, which is not a load figure.
