Cheers, and thank you!
I have a vanity domain which I use to exercise my internet independence :) I've been using PowerDNS with a hidden master, public secondaries, dns updates with lua authorization for dynamic ips and let's encrypt for years. Also the recursor for local systems.
I received great help and had some fun chats on IRC in the beginning. PowerDNS has been a great part of my "infrastructure". My only complaint is that packagers and other naming can't choose between 'powerdns' and 'pdns' :)
