Took me 3 hours to find a single typo in my firewall rule that was blocking all traffic

One wrong character in an IP address and the whole office couldn't send emails for a day, has anyone else had a tiny mistake like that wreck their whole setup?

Yeah, you ever spend hours staring at something and it's literally one character off? That hits hard. I spent a whole Saturday once because I mistyped a subnet mask by one number. Everything looked fine on paper but nothing worked. It's like the universe punishing you for being tired. Solidarity, friend.

Tbh @martinez.karen I gotta push back a little. One Saturday because of a subnet mask? That sounds like part of the job honestly. People act like it's this huge tragedy but we all signed up for this. You mess up, you learn, you fix it. It's not like the universe is targeting you personally. It's just how this stuff works. I've lost way more than a Saturday to stupid mistakes and I just shrug and move on. It's not that serious.
