Releases an expired Anti-DDoS Pro or Anti-DDoS Premium instance.
If an Anti-DDoS Pro or Anti-DDoS Premium instance expires, DDoS mitigation stops. The instance stops forwarding traffic seven days after it expires.
- We recommend that you renew your instance before it expires. This eliminates the impacts on service protection and traffic forwarding. You can call the DescribeInstances operation to query the expiration time of all instances. If you want to renew your instance, log on to the Anti-DDoS Pro console.
- If you do not plan to renew your instance, switch the service traffic back to the origin sever before your instance expires. To switch the traffic back, change the service IP address to the IP address of the origin server or modify the CNAME record to stop forwarding service traffic to Anti-DDoS Pro or Anti-DDoS Premium. This avoid service interruptions caused by the expiration.
You can call this operation to release a specific instance after the instance expires.
