> People don't believe me when I say how much DNS matters.
That's weird to me. I have been working in sysadmin/DevOps for over a decade, but it did not take me very long to learn that DNS outages cause massive problems.
Right, but everybody has to learn that at some point. And I happen to be somebody who teaches such things. The importance of DNS is hard to overstate, but I go to great lengths to do exactly that, to make a point ;)
