Dear Customer,

The log storage feature for Anti-DDoS Native 2.0 (Subscription) was officially launched on August 13, 2026. Starting immediately, you can purchase a dedicated log storage specification for your instance when creating a new instance or upgrading an existing one. Once enabled, the system automatically creates a dedicated Logstore and continuously delivers mitigation logs to it.

Migration Notice for Public Preview Users

If you have enabled the free public preview of the mitigation analysis feature, please note the following changes: If you previously enabled the free public preview of the mitigation log feature, please note the following changes:

End of log delivery: After December 31, 2026, new logs will no longer be written to the Logstore created during the public preview period.

Recommended action: Purchase the log storage specification through an instance upgrade before December 31, 2026. After the upgrade, subsequent logs will be automatically delivered to the Logstore associated with the new specification.

Historical logs: Logs generated during the public preview period will not be affected. You can continue to query them in the original Logstore, subject to the default retention policy of Simple Log Service (SLS).

How to Upgrade:

Log on to the Alibaba Cloud Management Console > Anti-DDoS Native > select the target instance > Upgrade > select the log storage specification > confirm the purchase.

If you have any questions about the log storage feature or the migration plan, please contact your account manager. We will be happy to assist you.

Thank you for your continued support of Anti-DDoS Native.
