My bad - I'd mailed this mistakenly to an individual and not the list. ---
I am currently running BIND 9.18.18-0ubuntu0.22.04.2-Ubuntu. I am sometimes seeing that I don't have resolution for some FQDN in forwarder zones. Usually it works, sometimes I don't get resolution. Interesting I failed resolution for an FQDN yesterday and while relieved to see that I failed to get resolution on the authoritative server I later was able to resolve on the authoritative server but still failed on the local forwarding server. Wondering what is going on there. Conjecture - caching the failed response for some period of time? If so, disable caching for the problematic forwarder zone? Some other issue? If so what might it be, how can I test for it and how do I resolve/work-around it?
