----------------------------------------

yes tagged the component; not sure I understand exactly what is meant by which version this
'surfaces' on - is it affects version or fix version ?

In such cases the storage driver needs to detect and handle the exception. We put in this
logic to do the retries however the condition to check for the exception is not always met
due to inconsistency in which the manner the error code is passed back. Instead the retry
logic should check for http status code (503) which is more reliable and consistent check
