  1. Upgrade impact: During the upgrade, some IPs subject to stronger security checks will need to be re-authenticated, which will cause the TCP connection to be interrupted briefly several 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.
