- Before you terminate your WAF instance, update the DNS records for your protected website domain names to point back to your origin servers. For instructions, see Modify DNS records.
- After you terminate your WAF instance, all configuration information for your website domain names is permanently deleted. If traffic is still routed to the WAF instance, requests cannot be forwarded, and your website domain names will become unresponsive.
