-- This API is in preview release for Amazon Connect and is subject to
-- change.
--
-- Returns the current state of the specified instance identifier. It
-- tracks the instance while it is being created and returns an error
-- status, if applicable.
--
-- If an instance is not created successfully, the instance status reason
-- field returns details relevant to the reason. The instance in a failed
-- state is returned only for 24 hours after the CreateInstance API was
-- invoked.
