I thought self-hosting DNS would be easy, since it is 40 year old tech now.

Even now, like you, I get the occasional (ie. once per year) named segfaults or it randomly stops responding over TCP.

Few SaaS products are less effort than one reboot per year, but still worth it IMO.

Since then I've started using CoreDNS, which does seem easier to monitor. (I don't know if it's faster or more reliable, but it has a lot of ways to figure out what's going wrong. As it turns out, DNS causes people a lot of trouble these days when they use it for service discovery, and their services discover each other hundreds of times a second. So that's why DNS servers grew APIs and observability features.)
