August 17 Anti-DDoS Pro Upgrade Notification

[Alibaba Cloud] [Anti-DDoS Pro] [Upgrade Notice]
Upgrade window: Beijing time 00:00-06:00 on Aug 17, 2018 (PST 08:00-14:00 on Aug 16, 2018)
Upgrade content: Anti-DDoS Pro server rooms in Hong Kong will perform upgrade operations and add Back-To-Source CIDR blocks.
Upgrade impact:
1. During the upgrade, the TCP connection will be flashed 4-8 times. The flash will not affect the short connections and the long-connection services with automatic reconnection business. Please make sure your applications include a reconnection mechanism to ensure fault tolerance.
2. New Back-To-Source CIDR blocks will be added after the Anti-DDoS Pro server rooms are upgraded in Hong Kong. If you selected your Anti-DDoS Pro node as Hong Kong, please pay attention to the Back-To-Source CIDR blocks added this time. If there is an access whitelist setting at the front of the server, please add those new IP segments to the white list before August 15 to avoid the subsequent problem of unreasonable service due to upgrade of the equipment room. Thank you for your cooperation.

You can check the latest Anti-DDoS Pro Back-To-Source CIDR blocks information in the upper right corner of the website configuration page in the console. The Back-To-Source CIDR blocks that will be upgraded this time is as follows:
