To add to that, I just manually updated another running webserver, and boom. The apache+php webserver uses DNS to resolve the database server, which it can no longer do after the update, bringing the site down.

It sends these incorrect TYPE62321 DNS queries to our DNS server.

22-Mar-2017 05:33:01.205 queries: info: client 172.16.x.x#59821 (mysql.internal.domain): query: mysql.internal.domain IN TYPE62321 + (172.16.x.x)

In this case, restarting apache2 clears the issue. I don't know if anything else also needs restarting (so i did a reboot after to be sure).

If it helps, I also have traditional resolv.conf instead of resolvconf
