As people used to say "No one was ever fired for choosing IBM."

If people lose enough money then they will come up with contingency plans etc. that may even work in the next outage! Absolutely no one will be held responsible though. The kind of management folks that made those decisions will just turn around and work on those contingency plans, and everyone (including themselves) will believe that they had been doing so all along.

At least that's my experience in big corporations.
