Wow. That's the first time in my 25+-years on the internet I've ever heard someone say that dns "just works".

- otabdeveloper4 3y agoWait till you find out about the cascading failure modes of TCP. You're in for the ride of your life.
- seanhunter 3y agoI have run TCP/IP networks of thousands of machines before all the automated tooling that's around these days to make this not cause you to loose your sanity. I've seen many of the possible cascading failure modes there are to see at this point[1]. I stand by my claim that DNS is one of the most unreliable parts of the jenga tower though. [1] eg the first time I had root on a unix box I accidentally advertised it as a gateway over bgp and had all the "outbound" tcp traffic for the business park our office was in and a small ISP coming into my box and timing out. Yeah bgp and routing protocols are also common causes of failure, but DNS is worse.
