Before your Anti-DDoS Pro or Anti-DDoS Premium instance is released, you can manually renew the instance to extend the subscription period. To prevent your services from being adversely affected by instance expiration, you can also enable auto-renewal before your instance expires. This way, Alibaba Cloud automatically renews the instance when the instance is about to expire. This topic describes how to manually renew an Anti-DDoS Pro or Anti-DDoS Premium instance. This topic also describes how to enable auto-renewal for the instance.

Prerequisites

An Anti-DDoS Pro or Anti-DDoS Premium instance is purchased. For more information, see Purchase an Anti-DDoS Pro or Anti-DDoS Premium instance.

Supported asset types

You can renew the following types of Anti-DDoS Pro or Anti-DDoS Premium instances:
  • Anti-DDoS Pro instance of the Profession mitigation plan
  • Anti-DDoS Premium instance of the Insurance or Unlimited mitigation plan
  • Anti-DDoS Premium instance of the MCA mitigation plan
  • Anti-DDoS Premium instance of the Sec-MCA mitigation plan

Impacts of instance expiration

If you do not renew your Anti-DDoS Pro instance in time after the instance expires, your services are adversely affected. The following table describes the impacts.
Time period Protection capability Traffic forwarding Instance configuration
From the expiration date to 7 calendar days (excluded) after the expiration date The instance provides only the basic protection against attacks of 5 Gbit/s.

If you renew your instance within this time period, the instance continues to provide the protection capabilities based on the plan that you purchased.

The instance still forwards service traffic. Instance configurations are retained.
7 calendar days (included) after the expiration date to 30 calendar days (excluded) after the expiration date The instance provides only the basic protection against attacks of 5 Gbit/s. The instance no longer forwards service traffic.
Warning If you no longer need Anti-DDoS Pro, you must switch service traffic from the Anti-DDoS Pro instance to the origin server seven calendar days before the expiration date. Otherwise, access to your services may be adversely affected. If you want to switch service traffic, make sure that the domain name of your website does not map to the CNAME assigned by Anti-DDoS Pro. You must also make sure that your non-website service does not use an exclusive IP address provided by the instance.
If you renew your instance within this time period, the instance continues to forward service traffic, and you do not need to configure the instance again.
Instance configurations are retained.

Manually renew an instance

Before your Anti-DDoS Pro or Anti-DDoS Premium instance is released, you can manually renew the instance and retain the original configurations of the instance.
Notice If the instance is released, you cannot manually renew the instance. For more information, see Impacts of instance expiration.
We recommend that you manually renew your instance based on the following suggestions:
  • Anti-DDoS Pro instance: Renew your Anti-DDoS Pro instance any time before the expiration date or within seven calendar days after the expiration date. This way, the forwarding of service traffic is not adversely affected.
  • Anti-DDoS Premium instance: Renew your Anti-DDoS Premium instance any time before the expiration date or within 30 calendar days after the expiration date. This way, the forwarding of service traffic is not adversely affected.

You can perform the following steps to manually renew your instance:

  1. Log on to the Anti-DDoS Pro console.
  2. In the top navigation bar, select the region where your instance resides.
    • Mainland China: If you select this region, the Anti-DDoS Pro console appears.
    • Outside Mainland China: If you select this region, the Anti-DDoS Premium console appears.
    You can switch the region to configure and manage Anti-DDoS Pro or Anti-DDoS Premium instances. Make sure that you select the required region when you use Anti-DDoS Pro or Anti-DDoS Premium.
  3. In the left-side navigation pane, choose Assets > Instances.
  4. Find the instance that you want to renew and click Renew in the Actions column.
  5. On the Renew page, set Plan, which specifies the renewal duration. Read and select Terms of Service. Then, click Buy Now. Renewal
  6. Complete the payment.

You can check the new expiration date of your instance on the Instances page. The subscription period is extended based on the specified renewal duration.

Enable auto-renewal

You can enable auto-renewal only within two or more calendar days before the instance expires. If your instance is about to expire the following day, you must manually renew the instance.

You can perform the following steps to enable auto-renewal for your instance.

  1. Log on to the Anti-DDoS Pro console.
  2. In the top navigation bar, choose Expenses > Renewal Management. Renewal Management
  3. On the Manual tab of the Renewal page, find the instance that you want to renew and click Enable Auto Renewal in the Actions column.
  4. In the Enable Auto Renewal dialog box, select an auto-renewal period and click Auto Renew. Enable auto-renewal

After you enable auto-renewal for the instance, you can view the auto-renewal settings of the instance on the Auto tab. Alibaba Cloud automatically deducts fees from your account balance to renew your instance nine calendar days before the expiration date. Then, the subscription period of the instance is extended based on the renewal duration that you specified.

If you no longer need auto-renewal for your instance, you can enable manual renewal for your instance on the Auto tab.
