Kube-dns (or CoreDNS in newer clusters) is pretty stable in my experience. It's still a very good idea to run more than one replica so that you can tolerate a single node failure, but if DNS failures are "fairly normal" that definitely warrants some additional investigation.

Most dns problems in kubernetes, in my experience, can be traced to udp failures due to the iptables kubeproxy backend.

Thanks we did look into it but not as thoroughly as probably needed. Switching out from Alpine fixed pretty much all our issues.
