Well isn't that an interesting coincidence. That story just reminded me of this from a few years ago:

The Wall Street Journal, picking up from an earlier report by Foreign Policy magazine, explores that question Wednesday in a long account about what happened at PG&E Corp.'s Metcalf transmission substation — an event that has received relatively little attention until now.

"The attack began just before 1 a.m. on April 16 last year, when someone slipped into an underground vault not far from a busy freeway and cut telephone cables.

"Within half an hour, snipers opened fire on a nearby electrical substation. Shooting for 19 minutes, they surgically knocked out 17 giant transformers that funnel power to Silicon Valley. A minute before a police car arrived, the shooters disappeared into the night.

"To avoid a blackout, electric-grid officials rerouted power around the site and asked power plants in Silicon Valley to produce more electricity. But it took utility workers 27 days to make repairs and bring the substation back to life."

I guess they were getting some hands on training back then.
