【Upgrade Region】:
Partial instances in Availability Zone E of the East China 2 (Shanghai) region.
【Upgrade Impact】:
Hologres will undergo an upgrade of the underlying hardware environment, requiring a restart of some relevant instances. We recommend that you log in to the console and restart the relevant instances before the latest operation time specified in the internal message to complete the infrastructure upgrade.(Please refer to the messages and emails sent to your account for specific examples of the impact. If you haven't received any upgrade messages, in-site messages, or emails, you are not affected.)
If the restart is not performed, the Hologres team will restart the instance at the latest operation time specified in the internal message, during which the service will be briefly unavailable.
We apologize for any inconvenience caused and appreciate your understanding. If you have any questions, please feel free to contact us through the ticket system. For more information, please refer to the internal message.
