Hypershift Konnectivity fails to add AWS ISO (classified) domains to the ingress operator's NO_PROXY list.  This prevents necessary direct (not proxied) communication with endpoints in those namespaces.  The current list of cloud domains configured to be routed through the management cluster and not through Konnectivity can be found at https://github.com/openshift/hypershift/blob/main/support/konnectivityproxy/dialer.go#L462-L485.  The AWS ISO region domains that need to be added are:

".c2s.ic.gov"
".hci.ic.gov"
".sc2s.sgov.gov"
