Instead act in a correct way to handle those errors.
Two remedies from my side:
1. 503 normally occurs when your backend does not respond. Increase you
timeouts. Connect timeout by default is 0.004 sec.
2. Redirect it to another URL using vcl_error. Intelligence with
elegant user experience.

Subject: Alert on certain error like 503
Hi,
Can varnish be made to send out an alert (mail) in case of an error like
503? I do have a monitoring solution but i can't add all the urls for
monitoring. Sometimes varnish gives a 503 and i need to be alerted during
that time.
Another option can be to keep looking for 503 errors. log them as they occur
and keep watching that file.
ShiB.
