503 Error with Varnish - What does this mean?

[Kervin L. Pierre]

Varnish throws 503 errors for a variety of underlying reasons.  You may need to check "varnishlog" to get some more information, the "FetchError" tagged messages will help you narrow down the cause.

It can be that one of a variety of timeout values have been exceeded, backend is intermittently available, etc. 

Best regards,
Kervin
