+#### DNS Health checks
+DNS Health checks has been enabled on the DNSPolicy. These health checks will flag a published endpoint as healthy or unhealthy based on the defined configuration. When unhealthy an endpoint will not be published if it has not already been published to the DNS provider, will only be unpublished if it is part of a multi-value A record and in all cases can be observable via the DNSPolicy status. For more information see [DNS Health checks documentation](../dns/dnshealthchecks.md)
+
+Check the status of the health checks as follow:
+
+```bash
+kubectl get dnspolicy ${KUADRANT_GATEWAY_NAME}-dnspolicy -n ${KUADRANT_GATEWAY_NS} -o=jsonpath='{.status.conditions[?(@.type=="SubResourcesHealthy")].message}'
