For a few days, I've been seeing new messages like this in the logs, once per day per server:
freshclam[1133]: Sat Jul 27 01:49:03 2019 -> *Can't query daily.25523.93.1.0.2606470000000000000000006810da54.ping.clamav.net Some investigation suggests that this is failing because ns1a.clamav.net (etc.) have DNS NS records delegating *.ping.clamav.net to "ns4.clamav.net", but ns4.clamav.net does not work.
