I personally strongly disagree with this. ServFail is a signal from the authoritative operator that something is amiss, and is in practical terms is not really distinguishable from being unable to reach them. It's not just a "funny answer". If the resolver was previously able to get good answers for the same query but is now getting the server declaring things are whack, I don't see how passing through the ServFail helps anything, and it harms the intended resiliency of this whole endeavour. _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
