If you're wondering whether this is related to the sniper attacks on electrical transformers in 2013, don't worry - despite having apparently no idea who did either, the FBI is pretty sure there's no connection.

"On April 16, 2013, suspects clipped fiber-optic cables outside San Jose before snipers opened fire on electrical transformers at PG&E's Metcalf Transmission Substation, causing more than $15 million in damage.

According to the FBI, the recent spate of fiber cuts are unconnected to the sniper attack on the Metcalf substation. No one has been arrested in connection with that attack."
