Aside from not dogfooding, what would have reduced the impact? Because "don't have a bug" is .. well it's the difference between desire and reality.

Not dogfooding is the software and hardware equivalent of the electricity network "black start" -you never want to be there, but somewhere in the system you need a honda petrol generator, which is enough to excite the electromagnets on a bigger generator, which you spin up to start the turbine spinning until the steam takes up load and the real generator is able to get volts onto the wire.

Pumped Hydro is inside the machine. It's often held out as the black-start mechanism because it's gravity, there's less to go wrong, but if we are in 'line up the holes in the cheese grater' space, you can always have 'want of a nail' issues with any mechanism. The honda generator can have a hole in the petrol tank, the turbine at the pumped hydro can be out for maintenance.
