Rolling portions of the Bay Area (but by no means all, or even most) had well communicated power outages due to weather conditions during that time.

Aka there was plenty of time for people to know what is going on, no one was really surprised, agencies had time to prepare and roll out contingencies, etc.

In this case, no one seems to really know what caused it, let alone have had any warning. And Santiago is the national capital.

For all they know, someone intentionally crashed the grid in order to take the country.

What would you expect the US gov’t to do if Washington DC suddenly and unexpectedly completely lost power? I guarantee it would be pretty much the same thing.
