It appears 9.16.1 is subject to a DOS attack, to which I seem to have fallen victim: https://kb.isc.org/docs/cve-2020-8617 There's a port called bind9.16.11, which is compiling now, but it's unclear if that's adequately patched. The CVE calls for 9.16.3 as the fixed version. Thanks for reading! bob prohaska
