This page has procedures for finding and setting maintenance windows for Cloud SQL instances. To learn more about how and why Cloud SQL performs maintenance, see the Overview of maintenance on Cloud SQL instances.

If you've opted in to receive maintenance notifications, then Cloud SQL sends you an email notification when a maintenance update is available for your Cloud SQL instance. Cloud SQL sends a notification before the maintenance rollout and then proceeds to apply the update to groups of instances on a weekly schedule. You can control how much advance notification you receive before your instance receives the maintenance update by selecting the maintenance timing for your instance.

You have the following options for scheduling the timing of your maintenance update:

If you select Any or don't configure this setting, then the maintenance update can happen at any time, but typically happens within the first week of the rollout.
If you select Week 1 (also referred to as preview and canary), then the maintenance update happens 7 to 14 days after the maintenance notification is sent out.
If you select Week 2 (also referred to as production and stable), then the maintenance update happens 15 to 21 days after the notification is sent out.
If you select Week 5, then the maintenance update happens 35 to 42 days after the notification is sent out.

If you make changes to your maintenance window setting while the instance is already undergoing maintenance or is scheduled for maintenance, then the changes don't take effect immediately. These changes are reflected in future maintenance events.

Before you begin

Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.
In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

Opt in to maintenance notifications

Before you opt-in to receive maintenance notifications, you must set a maintenance window on an instance

Go to the Communication page. Go to Communication
In the row for Cloud SQL, Maintenance window, select the radio button under Email to turn it ON.

Each user that needs to receive notifications must opt in separately.

Find maintenance notifications in the Google Cloud console

You can view maintenance notifications in a few places in the Google Cloud console:

On the Logs explorer page in the Google Cloud console. Use the All logs name drop-down to search for maintenance-events, then click Apply. If maintenance is scheduled for an instance, then the log shows the name of the instance and its scheduled maintenance start time.
When an instance is scheduled for maintenance, the date for maintenance is listed on the Instances page in the Maintenance column. The Maintenance column is usually hidden, but it displays automatically when maintenance is scheduled. You can also select Maintenance from the Column display options () if you want the Maintenance column to always show up.
Alternatively, you can select an instance to go to the Instance details page. If the instance is scheduled for maintenance, you will see a message in the Maintenance pane.
Go to Cloud SQL instances

Find scheduled maintenance using the API gcloud

To check for upcoming scheduled maintenance, use the following command:

gcloud sql instances describe INSTANCE_ID

Replace the following variable:

INSTANCE_ID: The instance to check for scheduled maintenance.

In the response, look for the scheduledMaintenance section.

Reschedule planned maintenance

You can reschedule maintenance by using the Google Cloud console, the gcloud CLI, or the Cloud SQL Admin API.

If you set the maintenance timing of your instance to Week 1 or Week 2, then you can reschedule maintenance by up to 28 days.

If you set the maintenance timing of your instance to Week 5, then you can reschedule maintenance by up to 7 days. You must reschedule maintenance within this time period to ensure that the instance receives the maintenance update before the next quarterly maintenance rollout begins.

Console

In the Google Cloud console, go to the Cloud SQL Instances page.

Go to Cloud SQL Instances
Filter for the term Maintenance to list all instances scheduled for maintenance.
In the Maintenance column, click Reschedule.
In the Reschedule dialog, choose whether to apply maintenance immediately, reschedule it to happen at a specific time within the allowed deferral period as defined in rescheduled planned maintenance, or defer to the next available maintenance window.

gcloud

To reschedule maintenance on a Cloud SQL instance, run the following command:

gcloud sql reschedule-maintenance INSTANCE_ID \
  --reschedule-type=RESCHEDULE_TYPE \
  [--schedule-time=RESCHEDULE_TIME]

Replace the following variables:

INSTANCE_ID: The instance to reschedule.
RESCHEDULE_TYPE: Use one of IMMEDIATE, NEXT_AVAILABLE_WINDOW, or SPECIFIC_TIME.
If you choose NEXT_AVAILABLE_WINDOW, maintenance is rescheduled to the next available maintenance window following the current scheduled time.
RESCHEDULE_TIME: If you specify SPECIFIC_TIME for RESCHEDULE_TYPE, then you also need to set the --schedule-time flag to specify the new day and time for maintenance to occur. Uses ISO 8601 format. For example, 2020-01-16T16:56:00.000Z

For reference information, see gcloud sql reschedule-maintenance.

If you want to reschedule maintenance for up to 28 days, then check the version number of gcloud. If the version number is below 390.0.0_RC00, then reinstall gcloud.

To see how the underlying REST API request is constructed for this task, see the APIs Explorer on the instances:post page.

Note: If you reschedule maintenance for an instance at the same time as an existing deny maintenance period, then the deny maintenance period takes precedence and the maintenance event is skipped. Configure a deny maintenance period

You can configure a maximum of one deny maintenance period on a Cloud SQL instance at any given time. The deny maintenance period takes precedence over any scheduled maintenance window. If there's a conflict between the timing of a maintenance window and the deny maintenance period, the deny maintenance period overrides the maintenance window.

You can manually remove a deny maintenance period, whether it has already occurred or not.

To configure a deny maintenance period, set its start date, end date, and the time of day the interval begins and ends. A deny maintenance period can span from one to 90 days.

For start date and end date, there are two formats:

yyyy-mm-dd: indicates a specific date
mm-dd: indicates a date recurring every year

The start date and end date are UTC. To set the timezone, use the time field to adjust the start time. For example, the start date = 2020-10-10 and the time = 07:00:00 indicate the start time 2020-10-10 07:00:00 UTC (2020-10-10 00:00:00 PST)

For time, the format is: HH:mm:SS.

Hours are between 0 and 23 (inclusive).
Minutes and seconds are between 0 and 59 (inclusive).

Console

In the Google Cloud console, go to the Cloud SQL Instances page.

Go to Cloud SQL Instances

Deny maintenance period notifications

Maintenance window notifications aren't sent when the planned maintenance time falls within the deny maintenance period and are forbidden by maintenance deny period settings.

If you change the deny maintenance period settings to prevent maintenance at a previously scheduled time, then the Cloud SQL instance skips maintenance and sends a notification about canceling the maintenance. Cloud SQL sends this cancellation notice whenever the instance is scheduled for an update.

Notifications of planned maintenance are sent during the deny maintenance period, as long as such maintenance is scheduled to occur outside of that period.
