If you happened to notice the ship sitting off the coast awhile back, it was checking the undersea cables using a remote controlled underwater vehicle. There are multiple cables that exit the United States via the Central Coast. One in Montana De Oro, owned by MCI, goes to New Zealand. A Sprint-owned cable also exiting by Montana De Oro goes to Japan. Grover Beach also has a cable…this one owned by Global Crossing and goes to Austrailia.
There’s a lot of Internet data and phone calls passing through the Central Coast!
