Changes

We will be performing a network upgrade for the Alibaba Cloud WAF CNAME access clusters in Germany and Malaysia.

Impact

During this upgrade, you may experience 2-3 transient service interruptions, which can manifest as connection resets or rejections. For clients with automatic retry capabilities, service should resume in no more than a minute. We recommend monitoring your applications and preparing appropriate disaster recovery plans based on your system's architecture, such as client retries, origin failover.

We apologize for any inconvenience this upgrade may cause. If you have any questions, do not hesitate to contact us by submitting a ticket or calling our service hotline.
