Here's a little more context about the author's motivation: https://mathstodon.xyz/@csk/116162797629337132

> In my online undergraduate P5.js course, students are about to begin the module on motion and physics, including a bit of physics simulation using Matter.js.

When did things get specialized this much?

Earlier quoted context omitted.

The undersea cables actually connecting the entire internet. Sometimes sharks just take a bite of them, they're reasonable well protected but it's enough damage to cause outages and disruptions. It's the single pin under everything because there are a limited number of those cables especially in some regions so a single shark can take out the entire internet for some countries. http://www.mirceakademy.com/uploads/MSA…

I feel like having them as a single brick is a bit hyperbolic, since undersea cables are pretty redundant in most of the world. Get rid of one and traffic just routes around it. Ships have been routinely destroying cables in the Gulf of Finland and the Baltic Sea in the past couple of years without causing significant disruptions.

Well that depends on how much traffic that cable was supporting, how much free capacity is available on other cables heading to the same area, how much additional latency the rerouting will add and how sensitive to latency the rerouted traffic is doesn't it?

Ask and you shall receive: https://stacktower.io/

bro. it asks for the ability for some random github user to literally take over your private repositories.

Yeah, if it weren't for that, I think this would blow up. Plus, even if you get past that, if you try a larger project, it times out after 1 minute and gives up. But it's a pretty awesome idea!

Do satellite networks not move the needle in terms of capacity/reliability now?

No. They're not setup to be a principal route between two nations and most satellite networks until very recently didn't even route messages through other satellites but instead retransmitted them to a ground station with access to hardline internet. Even Starlink mostly does this still because it's way cheaper and easier.

Only mildly. There's not huge amounts of dark capacity just sitting around waiting to take over so if a major fiber connection goes down the remainder will get congested with the extra capacity. It won't cascade like a power outage but the remaining lines will slow down.
