During the upgrade, persistent connections of dedicated load balancers may be disconnected for seconds. You can try again to restore the connections.
Impacts on other cloud services:
DCS: Instances using the Proxy cluster will be intermittently disconnected. Ensure that your services have the automatic reconnection mechanism.
Cloud databases: Connections to the databases using the load balancer address will be intermittently interrupted. Ensure that your services have the automatic reconnection mechanism.
API Gateway: Requests sent through an API gateway may fail. Ensure that your services have the automatic reconnection mechanism, and you can try again to restore the connections.
CSE Nacos: Customer microservice instances may go offline and try to restore. Responses to client requests may time out. Please do not restart or upgrade microservice instances during the upgrade.
ModelArts: Persistent connections of dedicated load balancers may be disconnected, which may cause intermittent interruptions to the connections between ModelArts MAlite and the load balancer. Ensure that your services have the automatic reconnection mechanism.
