They weren't kidding, it is addictive! I'm surprised that zero undersea cables connect directly to the SF Bay Area, and how many cables there are in the bay around Seattle/Vancouver.

And the Far North Fiber connecting Norway, Ireland, Alaska (USA), and Japan, but none of the other countries it goes by on the way. I wonder why.
