You can engineer for any number of nines and still have massive outages.

  With that logic, you can do anything and it’s A-OK if nothing you do succeeds.

    That's not the point. 9s and SLAs are contractural obligations, not laws of physics that cannot be broken. I saw many systems engineered for a lot of 9s be down hard for much longer than 9s promised, most often due to perfect storm of issues. 9s are great, and communicate pretty well what system was designed for, but they are in no way hard guarantee that the system will be up.

    I mean...you tried. What are you supposed to do if you fail, quit and never come back? That's terrible logic too.
