- For the paired on-premises sites, theCloud Servicereports a red status for all the pairings incoming from on-premises and outgoing to on-premises. The pairedOn-Premises to Cloud Director Replication Applianceinstances continue to report a green status for pairing to cloud and the replications from on-premises to cloud proceed according to their RPO. To restore the replications from cloud to on-premises, you can restart theOn-Premises to Cloud Director Replication Applianceinstances or you can repair all on-premises sites with the cloud site.
