重新排定維護時間
如果產品支援重新排定維護作業，您可能會在記錄的說明欄位中找到重新排定維護作業的連結。
例如，說明可能如下所示：
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.
