The InsufficientDBInstanceCapacity
error can be returned when you try to create, start, or modify a
DB instance. It can also be returned when you try to restore a DB instance from a DB snapshot. When this error is
returned, a common cause is that the specific DB instance class isn't available in the requested Availability Zone.
You can try one of the following to solve the problem:
-
Retry the request with a different DB instance class.
-
Retry the request with a different Availability Zone.
-
Retry the request without specifying an explicit Availability Zone.
