> DNS broke my site for three hours. But now I actually understand it I have been broken for three decades and I still don't understand DNS. It is a simple protocol but people use it in complicated manners.
why you need DNS for at server? just use hosts file. why your server would need to resolve domains on the internet? client yeah, server no.
You have to go back five decades if you want to use a host file. My point is that cache and making are the three hard things in computer science DNS has had both problems several times. I choose DNS over hosts files every time.
EDIT I might be off by one here.
