If your servers go down while processing an HTTP post from Digital River and your endpoint does not respond, Digital River will try again at a configured interval. Digital River configures clients to retry transport failures once an hour for a maximum of 48 hours by default. Once the 48 retries are exhausted, different processes respond based on unique business rules. Generally, Digital River monitors the number of retries and looks into the issue when all retries are exhausted. You can configure the interval and number of retries.
