Facebook (Meta) international cable expansion: animated map

That FB/Meta is buying into cable systems does not surprise me, considering how the submarine cable industry is structured and the massive scale of FB/Meta. Cables have massive massive capex to build and relatively tiny opex. The cost structure is completely front-loaded and if you want to be paying the lowest cost prices and you have a large enough requirement, the best way to do this is to be part-owner on cable systems (or an IRU https://en.wikipedia.org/wiki/Indefeasible_rights_of_use).
Edit a bit because I see this line here: partial ownership over 13% of the world's total length of backhaul infrastructure
Basically they are adding up the length of all the cables where FB/Meta have any ownership interest (or perhaps just IRUs) and dividing by the total number of submarine cable length. This is wrong for a number of reasons. These cables are shared in a number of ways. Firstly, each cable contains multiple fiber pairs, in some of these FB/Meta is using only 1 of 6 pairs. Secondly, each fiber is further subdivided by extremely precise DWDM technology (https://en.wikipedia.org/wiki/Wavelength-division_multiplexi...) which allows multiple signals to travel along the same fiber. Finally (and less commonly) fibers are divided into segments. This is more common in SE Asia and Africa where a single cable is really a system which may land at 10++ locations, each segment can be a unique route, or sometimes some fibers in the system bypass some locations, sometimes some fiber pairs completely bypass some landing points. Sometimes just some optical channels within a single fiber are diverted to a landing point! The total system design is incredibly complicated and reducing it to this 13% figure is poor. It is completely plausible that on some of these systems that FB/Meta are using <1% of the design capacity.
There is an exception to big tech companies collaborating with rivals on the underwater infrastructure of the internet. Google, alone among big tech companies, is already the sole owner of three different undersea cables, and that total is projected by TeleGeography to reach six by 2023.
Google has built and is building these solely owned-and-operated cables for two reasons, says Vijay Vusirikala, a senior director at Google responsible for all of the company’s submarine and terrestrial fiber infrastructure. The first is that the company needs them in order to make its own services, such as Google search and YouTube streaming, fast and responsive. The second is to gain an edge in the battle for customers for its cloud services.
I’ll just leave this here.

It kinda is. Interestingly a lot of these seem to be divided up by fiber. E.g. for CAP-1 it's a 6-pair system, FB/Meta own 5, Amazon owns 1.
This is from https://www.submarinenetworks.com/en/systems/trans-pacific/c...
I'm not sure what their source is though.
Calculating fiber pairs -> bandwidth is much much harder though and is an implementation detail which will absolutely change over time. I have no doubt that part of why FB/Google/Amazon want to own fiber this way (owning dedicated pairs) is so they can experiment with different WDM technologies.
Their capacity for failure in the overall system is far higher than the traditional companies who are selling circuits and must design things for many nines of reliability.

Simply one of the greatest films of all time.

I know he's the "bad guy" but I suspect I (many of us?) have been subconsciously channeling Cosmo since I saw the movie as an impressionable kid.

All prior guesses have always been right, but information control changes name and shape every few decades. :)
Reminds me of the transformation of the character Media to New Media in the TV show American Gods.
Also, I feel these kinds of things would ideally be managed by the state - in the same way that highways are? I mean, data is 'the commons' as a public sidewalk. I loathe to think some of our governing bodies are not up to the task, but, by gosh, they should be.

Also interesting to note the Bering Strait is not used, despite it being the only land almost connecting the West and the Far East.
