This has to be the worst possible way to present this. Just give us a, you know, MAP. With openable annotations and panning so we aren't locked in some view we didn't navigate to with tons of info about something we didn't actually seek out.

Here's one with an imaginative domain name

So is dijibouti some massive switching station hub or do those cables just go by it underwater?

My understanding is most of the multipoint cables are not switched at every point, it's more of a bundle of cables where each point gets a strand or two to every other point (or selected points, maybe the anchor points connect to all others, but minor points might only connect to the anchors and not each other).

That said, Djibouti is a major cargo transport hub for Ethiopia, and is probably a network transport hub as well. Ethiopia is the 2nd most populated country in Africa and that would justify a lot of cable landings.

How do these cables split in the middle of the ocean? Is there a fiber switch laying on the ocean floor?

No idea of what precise sort of hardware is there, but the fact is that these cables consist of a bunch of fibers. Dozens of them typically, quick search suggests up to 144, but I doubt that's a physical ceiling. So I suppose they make a branch when needed, with some number of fibers going to another direction.

It's interesting how Europe-Asia interconnects are so small relative to US-Asia and US-Europe.

This is only undersea cables. Europe and Asia have overland connections too. But mostly it's because both continents do more business over the internet with the US than with each other.

I love these maps, and I'm glad they provide downloads like [1]. I wish the resolution was a bit higher. As it is the names of the towns on the coasts can be read with difficulty. [1] https://submarine-cable-map-2023.telegeography.com/images/Su...

Wow, that map is very political. Israel is not mentioned by name, but the Palestinian Territories are.
