What is the structure of the Internet built on and is there any chance of laying down a world system?

Question

Computer networks

Good night. Something flooded me. You can put a piece of iron with heavy loads, but the Internet is in fact a bunch of pieces of iron that store data on themselves and exchange them. What, in theory, could kill the entire system?

Answer 1

"AS7007 Incident". The first time the Internet broke was in April 1997. There was a bug in the software of one router from the autonomous system 7007. At some point, the router announced its internal routing table to its neighbors and sent half of the network into a black hole.
"Pakistan vs YouTube". In 2008, the brave guys from Pakistan decided to block YouTube. They did it so well that half the world was left without seals.
"Capture of VISA, MasterCard and Symantec prefixes by Rostelecom". In 2017, Rostelecom mistakenly started announcing VISA, MasterCard and Symantec prefixes. As a result, financial traffic was directed through channels controlled by the provider. The leak did not last long, but the financial companies were unhappy.
"Google vs Japan". In August 2017, Google began to announce the prefixes of major Japanese providers NTT and KDDI in some of its uplinks. The traffic was sent to Google as transit, most likely by mistake. Since Google is not a provider and does not allow transit traffic, a significant part of Japan was left without the Internet.
"DV LINK has taken over Google, Apple, Facebook, Microsoft prefixes." In the same 2017, the Russian provider DV LINK, for some reason, began to announce the networks of Google, Apple, Facebook, Microsoft and some other major players.
"eNet from the US has taken over the AWS Route53 and MyEtherwallet prefixes." In 2018, an Ohio provider or one of its clients announced the Amazon Route53 network and the MyEtherwallet crypto wallet. The attack was successful: even despite the self-signed certificate, a warning about which appeared to the user when entering the MyEtherwallet website, many wallets hijacked and stole part of the cryptocurrency.
There were more than 14,000 similar incidents in 2017 alone! The network is still decentralized, so not everything and not everyone breaks. But incidents happen by the thousands, and they all involve the BGP protocol that powers the internet.
