In general, the cloud/systems operator, in conjunction with the launch customer will build a dedicated facility for the classified stuff, and for the controlled stuff may have a dedicated facility, or have segments of the DCs in the US with extra security. for the classified stuff, there is a pretty rigorous list of requirements for the DC, and for any NOC that operates the service.
