Most certainly. You don’t land a cable in either the US or France without a classified annex to the license that provides for interconnection to their intelligence services.

Let's say they do tap the cables (I reckon they do too but in case they don't) what can they actually see if the traffic is encrypted?

And at 250tb passing by every second

Considering they do intercept, as widely documented, question is how do they see if traffic is encrypted?

Ah the old "entire digitized Library of Congress" per second metric

I always find comparisons using text data incredibly worthless. I'm sure a Shakespeare play or The Great Gatsby are barely a few megabytes. But if you asked Joe Shmoe on the street "In Great Gatsbys, how big was the last picture your iPhone took", they would rightly have zero idea. It's so useless.

I recall seeing a story in the past about how the NSA planted a misleadingly weak encryption library.

If the encryption used is flawed, they could see whatever they want.

Source, destination, message length, etc. Lots of interesting meta data to play with.

Pretty trivial. If it looks like random noise, and doesn't have a compression header then it's probably encrypted.

"What is the cost of doing something like this?" Their Oregon to Japan cable, 9000km and laid in 2016, cost $300M. https://www.computerworld.com/article/2939316/googles-60tbps...

That is at least 1 order of magnitude cheaper than I would have guessed. Mind boggling that it's cheaper to do that then buy like the 4th best meal delivery app in Canada or whatever.

That's is what I thought, years ago back when I worked for a big telco we actually had a small fleet of our own cable laying ships.

The fun thing was the company hand book had a whole other section of T&C allowances etc if you worked on a ship.

Agreed, number of books stacked end to end to reach the moon is much more intuitive.

Easy! It's just three olympic sized swimming pools worth of dollar bills stacked to the moon in bits.
