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.)
