This topic describes how to deactivate a black hole that is applied to the IP address of a protection target.

Background information

After you purchase an Anti-DDoS Origin Enterprise instance, you can deactivate a black hole 100 times each month.
Note At the end of each month, the unused quota becomes invalid.

Before you manually deactivate a black hole, we recommend that you check the auto-deactivation time of the black hole in the Anti-DDoS Origin console. If the auto-deactivation time meets your requirements, we recommend that you wait for the black hole to automatically deactivate. For more information, see View the duration of a black hole.

Procedure

  1. Log on to the Alibaba Cloud Anti-DDoS Basic console.
  2. On the top of the page, select a region where the instance resides.
  3. In the Anti-DDoS Origin console, find the instance whose operations logs that you want to view, and click Deactivate Black Hole in the Actions column of the instance.
    Note You can deactivate a black hole. If an abnormal IP address exists in the instance, it indicates that the related protection target is in the blackholing state.
  4. On the Protection Target tab, find a protection target that is in the Blackholing state, and click Deactivate Black Hole in the Actions column of the protection target.
  5. The Deactivate Black Hole dialog box shows the remaining times that you can deactivate a black hole. Click OK.
    Note You may fail to deactivate a black hole due to the predefined policies for risk management of a backend system of Alibaba Cloud. The number of remaining times does not decrease when you fail to deactivate a black hole.

Result

If you fail to deactivate a black hole, you will receive a notification. We recommend that you wait a few minutes and try again. If you do not receive a failure message, it means that the black hole is deactivated.
