Conflicts and open questions
- Floor area: 120,000 sq ft on Netrality's page versus a 100,000 sq ft building in DCD's 2016 report.
- The page lists generator redundancy as N in the specifications but a caption mentions N+1 generators.
- Kept apart from 210 North Tucker because it is a separate building several blocks away; the lead may merge them as one Netrality St. Louis campus if preferred.
- Coordinates approximate, at the street address.
