>> Or just a distracted dev

And a distracted tester? And a distracted pipeline of regression tests?

No, the truth is way worst...

Either way it shows their QA and testing procedures are incompetent. It's just not acceptable for a utility like AWS to move fast and break shit. Should make you question whether it's safe or advisable to use any of their services.

It probably shouldn't be legal for banks, hospitals, governments, or any other critical infrastructure to be hosted on AWS if they do things like this.
