This topic describes how to purchase global advanced mitigation after you purchase an Anti-DDoS Premium Insurance Plan instance. If the two free advanced mitigation sessions of the current month are exhausted, global advanced mitigation is triggered when your services receive volumetric DDoS attacks again.

Prerequisites

You have purchased an Anti-DDoS Premium Insurance Plan instance. For more information, see Purchase an Anti-DDoS Premium instance.

Background information

If the two free advanced mitigation sessions of the current month are exhausted, but your services are still under volumetric DDoS attacks that exhaust the basic protection bandwidth, the global advanced mitigation sessions that you have purchased are used to provide unlimited bandwidth protection.

You can use global advanced mitigation for all instances that meet the usage requirements without binding global advanced mitigation to a specific instance.

Global advanced mitigation is triggered when the following requirements are met:
  • The Anti-DDoS Premium Insurance Plan instance is within the validity period.
  • The advanced mitigation feature of the account is not frozen.
    Note If the number of advanced mitigation sessions, including global advanced mitigation sessions, consumed by all instances under your account in the current month exceeds 10, the advanced mitigation feature is automatically frozen. You must wait until the next calendar month to use this feature. If your services receive frequent volumetric DDoS attacks, we recommend that you purchase an Anti-DDoS Premium Unlimited Plan instance to protect your services.
