Also, if a subscription WAF instance expires, you can terminate the WAF service to release the instance.

Background information

Note Before you can terminate the WAF service, make sure that the DNS records of the websites protected by your WAF instance point to the origin server. After you terminate the WAF service or release your WAF instance, all the configurations of the websites are deleted. If a request is still redirected to your WAF instance, the request cannot be forwarded to the origin server, and the access fails.


  1. Log on to the Web Application Firewall console.
  2. In the top navigation bar, select the resource group and region to which the WAF instance belongs. The region can be Mainland China or International.
  3. In the upper-right corner of the Overview page, click Terminate WAF Service.
    Note If you use a subscription WAF instance, the button appears only after the instance expires.
  4. Confirm that the DNS records of your websites point to the origin server. Then, click Confirm.
