“An attack on Silicon Valley telephone lines and an electric grid that took out transformers and fiber-optic cables remains unsolved a year after the nighttime raid that a federal official has decried as an act of terrorism.
The Federal Bureau of Investigation said Thursday it was still probing the April 16 attack, which happened a day after the Boston Marathon bombings. AT&T fiber-optic cables were snipped and sniper bullets destroyed 17 Pacific Gas & Electric transformers, disrupting service to the valley.”
