Have you noticed that when the blame #DNS meme starts flying the root is perfectly operational, there is rarely a mention of the big registry operators, BIND, Unbound, Knot, and PowerDNS are absent the conversation, and many who can craft a reasonable dig query are getting responses from local and public resolvers to debug?

Even with all the misconfiguration, added complexity on top of it, and burden of being used by practically every service on the Internet, we should marvel at how amazingly good the vast majority of the DNS performs despite our best efforts to overwhelm it with all the Internet junk we've created.
