## Associating DNS records with healthchecks
You can configure Route53 to associate DNS records with healthchecks for automated DNS failover using
`external-dns.alpha.kubernetes.io/health-check-id: <health-check-id>` annotation.
Note: ExternalDNS does not support creating healthchecks, and assumes that `<health-check-id>` already exists.
## Clean up
Make sure to delete all Service objects before terminating the cluster so all load balancers get cleaned up correctly.
