What the source record says
SOC 2 Type II carrier-neutral colocation facility in Old Sauk Trails Park on Madison's west side, with on-net access to Spectrum, TDS, AT&T, WIN, Lumen, US Signal and Verizon and no cross-connect fees. Distinct address from every tracked Madison-area site (US Signal WI01 at 222 W. Washington Ave., US Signal WI02/OneNeck at 5515 Nobel Dr. in Fitchburg, EdgeConneX MAD01, Lumen Madison 1).
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.

Compute Atlas 1.34.1 with retained prior rows and publication holds. This is a DataCenterData composite, not an unmodified publisher edition. This row uses the captured source from 1.34.1, source as of 2026-10-14T20:40:52.293Z.
That does not mean the row is wrong, and it does not mean no reviewed record exists for the same place. A link is added only when an identifier or source establishes the match.
