How can they even technically achieve that? You need to locate the exact location and drop some charges at presumably fairy deep depths Are these cables accessible by divers?

Why make it complicated. You pull an anchor along the bottom of the ocean and cut the cable.

It was commonplace where I grew up on an island, that our telephone line were cut by accident. Happened like 2 times in 15 years.

Wonder if the Spaceship will allow Musk to send up a serious satellite-based backhaul option. Sounds like there'll be some money to be made there, perhaps sooner than anticipated...

Best estimates I've found is that Starlink v2 sats have an aggregate capacity of 80Gbps each.

AAE-1 alone has a capacity of 40Tbps (the article says terabytes - that's wrong; EIG is There are at lot of submarine cables[1], though, so while I don't doubt that there will be people looking for contracts to use Starlink for some degree of extra redundancy and worst-case offload, the primary redundancy for these cables will be other cables, along other routes at least until Starlink gets a couple of generations further.

In neal stephensons 1996 classic wired article Mother Earth Mother Board theres a bit in there about why cables are not attacked.

"There is also the obvious threat of sabotage by a hostile government, but, surprisingly, this almost never happens. When cypherpunk Doug Barnes was researching his Caribbean project, he spent some time looking into this, because it was exactly the kind of threat he was worried about in the case of a data haven. Somewhat to his own surprise and relief, he concluded that it simply wasn’t going to happen. “Cutting a submarine cable,” Barnes says, “is like starting a nuclear war. It’s easy to do, the results are devastating, and as soon as one country does it, all of the others will retaliate."

This rule was broken last year and it will happen again with more and more frequency.

Earlier quoted context omitted.

Replacing entire bundles of fiber connectivity that is most likely in the 100 Terabit range per cable with space based solutions is not economical. Laws of physics still apply even to space based connectivity technologies.

Yeah I mean the whole point of my post is that maybe with laser inter-satellite links and a super heavy lift capability it might become economical at least for some use cases. E.g. the Pentagon might be quite interested.

Wouldn’t it be almost impossible to assign blame? The ocean is big and submarines are not easy to find. Maybe if you had other evidence like SIGINT?
