This bug was fixed in the package bind9 - 1:9.16.8-1ubuntu3.2
--------------- bind9 (1:9.16.8-1ubuntu3.2) impish; urgency=medium
* d/bind9.named.service: use systemd Type=forking to signal daemon init. This fixes a regression of #900788 where services whose startup depend on name resolutions may fail due to bind9 not being ready (LP: #1899902).
