How can we break the Internet forever?

Kill the undersea cables. About ninety nine percent of intercontinental data runs through a few hundred fiber lines at the bottom of the ocean, and there are maybe a dozen choke points like the Luzon Strait or the Red Sea where a handful of well placed cuts would sever entire continents from each other for months while repair ships queue up one at a time. Permanent is harder since humans would just rebuild, but you could get close by nuking the GPS satellite constellation and a chunk of geostationary orbit, because modern routing, timestamping, and backbone synchronization quietly depend on that signal more than anyone admits.

Flood the web with so much AI slop that nobody trusts a single post anymore, then nuke the few remaining undersea cables during a solar storm for the permanent offline. Dead Internet Theory is already halfway there in 2026 with bots over half the traffic, so just accelerate the slop until humans log off for good. Real collapse needs physical hits like coordinated fiber cuts plus geomagnetic chaos frying the backbone, because software alone always bounces back. That's the only way it stays broken forever instead of another headline outage.

You literally cannot do it with software because the entire distributed routing architecture was engineered to survive nuclear strikes, meaning your only actual option is an astronomical Carrington level solar storm that fries the physical power grid off the face of the Earth.

The operational parameters of the global network are not susceptible to a singular, singular point of failure that results in complete, irreversible cessation. A coordinated, kinetic attack on core undersea fiberoptic trunks spanning multiple tectonic plates would introduce insurmountable latency and physical breakage across major data arteries. That is the only vector with sufficient systemic impact to degrade global connectivity to a non functional state.
