根据所用服务，您或许可以重新安排更新时间或执行按需更新。如需了解各种产品支持的控制措施类型，请参阅支持的服务。
重新安排维护
对于支持重新安排预定维护的产品，您可能会在日志的说明字段中找到用于重新安排维护的链接。
例如，说明可能类似于以下内容：
Your instance is scheduled to undergo routine maintenance. As a managed service, Cloud SQL automatically updates instances to ensure that the underlying hardware, operating system, and database engine are reliable, performant, secure, and up-to-date. Most of these updates are performed while your Cloud SQL instance is up and running. However, certain system updates require a brief service interruption and are referred to as maintenance which typically happens once every few months.

执行按需更新
部分 Google Cloud 产品允许用户按需进行维护。对于这些产品，您可以在活动说明中找到有关如何执行更新的更多信息。
说明可能如下所示：
