Time:From 00:00 to 05:00 on January 10, 2024 (UTC+8): network upgrade for CNAME clusters in the China (Hangzhou) region.

Description: The network of the Web Application Firewall (WAF) CNAME clusters that reside in the China (Hangzhou) region will be upgraded.

Impacts: During the upgrade, two or three transient connections or denied connections may occur. If reconnection mechanisms are configured for clients, each transient connection or denied connection lasts for less than 1 minute.
