Blackout

Here’s another example of generic “equipment failure.” Not a lot of details, but I’m pretty sure the substation was not designed to fail. We should look at not just the equipment, but what additional safeguards are in place to prevent a single-point failure from blacking out a large section of a city.
Again, we don’t have details yet, but the label of “equipment failure” should make you think about digging a little deeper.
