In any significant war the Internet is going to go down. That's what has happened empirically in countries undergoing significant wars or social unrest, like Russia, Iran, Yemen, Ethiopia, Syria, Myanmar, and Afghanistan. While IP packet routing itself may have been designed to survive a nuclear war, there have been many centralized systems built on top of it (DNS? Edge caching? Cloudflare? Big Tech) that are essential to the functioning of what we know of as the Internet.

If your threat model includes war and you want to have some of the conveniences of the Internet, you should make plans for how to host local copies of data and develop local-scale communications for the people you regularly talk with. The Internet is too big of a security and propaganda risk for governments to allow it to continue to exist when they are engaged in a real existential war.

Some systems are anycast and available in many datacenters for bandwidth cost reasons. Netflix used to deploy content caches in ISP edges.

But any single central point of failure might break them. Things like, is this account paid? Dunno!

Netflix and Youtube both still use caches in ISP edges. The internet would melt without them.

Which is why bitcoin was always a ready really dumb idea as “end times hedge”

In the "end times" where computers stop working and we don't even have electricity, your dollars in your digital bank account will be equally useless, and dollar banknotes will be used as fire starter.

Bitcoin was never designed as a post-collapse currency.

Dollars work without electricity. Gold works. Bottlecaps work.

One of my friends speculated that bullets will be a great currency at the end of the world.
