I read a story in the print WSJ yesterday that shocked me. I tried to find it online, but couldn’t. Last April, a group of people cut some telephone lines outside San Jose and then proceeded to open fire on an electrical substation with high-powered rifles and destroy all the transformers. It was apparently the electrical substation that causes Silicon Valley to be well-lit. They fired for 20 minutes or so, then melted away into the night.
Authorities had to reroute some stuff and make a few power plants produce extra power to prevent the blackout. It took a month to repair the damage.
The police responding to the 911 call arrived 1 minute after the last transformer went down, and they found no one on the site. To this day, no one has been arrested. I have a few observations after the cut.
