REGISTRY-LOCK: The registry sets this status. The domain can not be modified or deleted by the registrar. The registry must remove the REGISTRY-LOCK status for the registrar to modify the domain. The domain can be renewed. The domain will be included in the zone if the domain has been delegated to at least one name server.

The domain will not be included in the zone. The domain can not be modified or purged; it can only be restored. Any other registrar requests to modify or otherwise update the domain will be rejected. The domain will be held in this status for a maximum of 30 calendar days.

If the registrar fails to provide documentation to the registry within 7 calendar days to confirm the restoration request, the domain will revert to REDEMPTIONPERIOD status. The domain status will be set to ACTIVE only if the registrar provides documentation to the registry within 7 calendar days to confirm the restoration request.
