FBI Investigating Fiber-Optic Cable Vandalism in Bay Area

The FBI is investigating an apparent coordinated attack on fiber-optic cables which left some Bay Area residents and businesses without phone, cable or internet this week.

FBI spokesman Greg Wuthrich said Tuesday’s attack is one of nearly a dozen to have hit the region during the last year. It occurred after someone entered an Alameda County manhole and clipped three fiber-optic cables, disrupting service for an unknown number of customers.

According to Broadband spokesman Mark Peterson, the severed lines primarily impacted suburban areas around Sacramento and Rocklin. At least two businesses have confirmed that their cables were compromised in the attack.

“It's a huge inconvenience, but it's not a comprehensive outage,” Peterson added. Officials say customers can expect slowed internet, TV, and phone service until the issue is formally resolved.

At least 10 Bay Area cities have seen fiber-optic cables sabotaged since July of last year, but investigators are unsure how the incidents are connected. More than 50,000 customers Santa Clara, Santa Cruz and San Benito counties lost service in 2009 following a similar attack.
