No mention of latency improvements?

Seems crazy since oversea transit (tcp & single-channel) is usually latency (or loss) bound.

I would expect it's better than going over public transit and legacy subsea fiber, but it would have been useful to see some comparison tests between POPs.

Is Google using this for consumer services (Gmail/Search/YouTube/Stadia) that don't run on GCP or is this only for GCP? If it's only for GCP, they are betting big, which is good.

Google uses gcp.

For everything? I was under the impression they still ran all the big stuff on their internal cloud with Borg and all the other infrastructure tooling they built.

I know there are many of these cables that have been around for years, but I am curious how are they physically secured? Especially where they transit from ocean to land? Is there some long underground/sea tunnel of conduit that the cable is routed through to the basement of some building? Or if you are walking along the beach somewhere is there just some cable running out of the ocean along the beach to some buildin…

You’re spot on. Most of the cables are either laid on the sea floor and up to a beach, or buried underneath beaches. The following link has some good background on what goes into laying cables and how they terminate.

As for physical security, there isn’t much on the sea floor. There are various instances of nation states tapping cables due to the ease of access when it comes to actually “listening” to the data. Obviously the issue there is getting to the undersea cable.

Earlier quoted context omitted.

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?

Nobody knows. Probably not.

But Snowden showed us that a lot of it is scooped up and warehoused. Maybe they can see your traffic in a decade or two?

> how are they physically secured

Multiple nations have specialised subs to tap into them. I doubt you'd find anyone willing to make such a guarantee. They are impossible to secure in any way and you need to rely on security assurances at different layers instead.

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.

A number of the first trans-atlantic cables landed in the tiny village of Heart's Content, Newfoundland. I drove through there on a road trip about a decade ago & stopped at the excellent museum in the old cable station, and was excited to make my way across the highway to the beach to see this exact thing. It turns out that the old cables are just.... left to rust on the beach. It's really amazing that these cables, originally a technological wonder & a bridge between entire continents, are just left to the elements once their useful life is over.

Do those come with pre attached NSA listening devices [1] ? [1] https://siliconangle.com/2013/07/19/how-the-nsa-taps-underse...

There's a reason the vast majority of undersea cables have at least one end in a Five Eyes country. No need to tap it in the middle of the ocean then!

Even if this is true, I think the simple reason might be that one of the five eyes country is US, which is probably the global hub for data and services used throughout the world. Also, Britain being near entrance of Europe from Atlantic, and Australia being near Asia would make economical sense for the cables to take that path.

I’ve wondered the same, you can image search and find some pictures. They just sort of come out of the water and go up the beach (I guess what else would happen? Hah) https://media.wired.com/photos/59546c71be605811a2fdcfd0/191:...

Guessing this would be more typical: https://cdn.cnn.com/cnn/.e/interactive/html5-video-media/201...
