I work in IT managing several government websites in my country. Due to my negligence checking a really simple thing while doing a configuration change, one of the websites throws an error for every single user who visits it.

This entire snafu could have been avoided if I had checked a simple thing. But I did not. I'm prepared to burn my Friday and weekend to fix this, but certain things I need are out of my control and in the hands of others. Again, the entire mistake could have been avoided if I'd just double checked.

At the minimum, this will cost me several hundred dollars, and maybe I'll get fired, but the business impact is much more severe than that.
