There is a rule of thumb to not ship anything on a Friday.

This was a Sunday!

And it didn’t seem to have been tested, so where was the Dev/UAT/Prod separation?

So many red flags, and I think anyone who has been in development for a while has had some product owner try to break procedures to force whatever pet project that is falling behind to hit some target to get their bonus/gain brownie points. It almost never goes well. But by this time the PO has a scapegoat because it’s no longer their fault it’s not working, it’s production’s fault. (Also it’s not always a PO, it can be a developer or anyone up to c-suite level)

Sigh
