Found out 47% of enterprise network outages come from bad DNS configs

I stumbled across a report from ThousandEyes that said this and it honestly blew my mind. Has anyone else found that DNS gets treated like a set-and-forget thing until something blows up?

and yeah people totally sleep on DNS until the CEO can't get to the website haha. it's wild how teams will obsess over their cloud configs or firewall rules but just assume DNS is fine forever. i've seen whole production environments go down because someone fat fingered a CNAME record during a "quick fix". honestly the real problem is that DNS debugging is kind of painful so most folks just cross their fingers and hope for the best.

Realize you've been living on borrowed time when the CEO's assistant calls asking why the company website just shows a white screen and you run nslookup and it's returning some garbage IP from a typo'd TXT record from 3 years ago. DNS is basically the plumbing of the internet, nobody cares until the toilet backs up and floods the basement. I remember one place I worked had a junior guy update a CNAME during lunch and took down the whole customer portal for 45 minutes before anyone thought to check DNS because "it was fine yesterday." It's like teams will have 12 alerts for CPU usage but zero checks for if your domain actually resolves correctly, total madness.
