Timestream for InfluxDB Multi-AZ deployments can only have one standby. When the deployment has one standby DB instance, it's called a Multi-AZ DB instance deployment. A Multi-AZ DB instance deployment has one standby DB instance that provides failover support, but doesn't serve read traffic.
Important
Your instance must have at least two subnets associated with it to execute Single-AZ to Multi-AZ updates. Once the instance is created, you can't modify its deployment mode from Single-AZ to Multi-AZ .
You can use the AWS Management Console to determine whether your DB instance is a Single-AZ or Multi-AZ deployment.
Using the AWS Management Console
Sign in to the AWS Management Console and open the Amazon Timestream for InfluxDB console
