Sven put a new application live. He sent an email to everybody:

“If it needs to be rolled back, here are the instructions to do it.”

Followed, of course, by short instructions as promised.

A few hours later we received an email (not a call or anything) from our outsourced operations team:

“Uhm, I mad a mistake – I did not see that ‘if’ and rolled the change back. What should we do?”

Making the mistake itself isn’t even that bad – it was easy to restore. But to send an easily-overlooked email is just beyond stupid.
