Posted on 11/16/2020
Upgrade window: 10:00-22:00, August 17th, 2020, Beijing time
Upgrade content: Adding Scrubbing Center in UK
Upgrade impact: During the upgrade, the service will not be impacted. In extreme cases, some IPs subject to stronger security checks will need to be re-authenticated, which will cause the TCP connection to be interrupted briefly 2 times. This will have minimal effect on short-term connections and long-term connections which have an automatic reconnection mechanism. Please make sure that you have a reconnection/retry mechanism in your application to enhance fault tolerance.After upgrading, the Anti-DDoS Premium will add new Back-To-Source CIDR blocks. If you are currently using the Anti-DDoS Premium and have access control policies for the source IP on the server side, please update the white list to include the following Back-To-Source CIDR blocks in time to avoid business impact caused by false interception.
The new Back-To-Source CIDR blocks list:
170.33.88.0/24
170.33.92.0/24
170.33.93.0/24
170.33.90.0/24
8.208.75.0/26
