Are My RDS DB Instances Still Available During Storage Scale-up and Instance Class Change?

Currently, you can scale up storage space and change the vCPU or memory of a DB instance.

When storage space is being scaled up, RDS DB instances are still available and services are not affected. However, you cannot delete or reboot DB instances that are being scaled.
During the change of the vCPU or memory, the network is intermittently disconnected for one or two times in seconds. For primary/standby DB instances, a failover may occur and services may be briefly interrupted. Changing the vCPU or memory takes 5 to 15 minutes.
After you change the vCPU or memory, the DB instances will reboot and services will be interrupted. Therefore, you are advised to change instance classes during off-peak hours.
