@TheGibson Was managing a terrible HR application and got overconfident while applying patches, went for the next one without a snapshot and it failed miserably (it didn't in our test env).

The HR department (hundreds of employees) was left unable to do any work for half a day. We didn't know at the time if it was going to be an easy fix or something that would let us struggle with our backups for *days*.

Been treating prod environments like unexploded bombs since then, which is what they are.
