The "phonebook of the Internet" has well outlived physical phonebooks, but that doesn't mean DNS is without its issues. There is a joke among incident responders that, even when you're sure the problem isn't DNS, it still ends up being DNS.
Aside from configuration issues, DNS is also a very valuable target for adversaries. In a paper presented at VB2019, Cisco Talos researchers Warren Mercer and Paul Rascagnères looked at two recent attacks against DNS infrastructure: DNSpionage and Sea Turtle. The latter attack involved the compromise of one country's DNS registry.
