We track 33 CyrusOne datacenter sites across 11 states, evidenced by building permits and public facility records. This counts sites we can tie to CyrusOne in public filings, so it is a floor rather than a complete corporate footprint: leased colocation space and sites permitted through unnamed LLCs may not be attributed here.
12 of the CyrusOne sites we track have permits indicating construction is under way, in Arizona, Virginia, Illinois, Iowa, Ohio.
