Upgrade Details
Alibaba Cloud will perform an upgrade on the transparent proxy clusters for the Web Application Firewall (WAF) service in the Indonesia (Jakarta) region.
Impact
During the upgrade window, some transparent proxy instances may experience transient connection interruptions or refused connections. For clients with an automatic reconnection mechanism, the duration of any single interruption is expected to be less than one minute. Please monitor your services and prepare a disaster recovery plan, such as implementing connection retries or failover to the origin server.
