The sorbs.net provides 15 NS records, from which at least 4 does not respond at all, thus recursive server has problem to get responses. The unbound (as caching recursive DNS), after it reaches certain count of errors, disables that domain for some time. When it is lucky to select working NS, then it gets response for dnsbl.sorbs.net, which yields another 18 NS, from which 10 doesn't responds. And the disabling repeats. When it is lucky to get that response, then unbound caches it and then it works for some time, until TTL expires. Then it start lottery again from start. This persist for long time, while i did not try to collect exact counts before. > We configured a private secondary for this and experienced exactly > zero issues. We are talking about their public DNS, your private mirror is, ehm, your private mirror. regards -- Slavko https://www.slavino.sk
