The Internet could be effectively shut down easily by turning off or manipulating the "root servers', which are controlled by an organization named ICANN. This would stop all domain names from resolving. By doing this, the Internet would still technically be operational, and could be used by connecting via IP addresses, but most Internet services would be unusable.

Theoretically, this could be achieved in a matter of hours.

The article below explains some of this: https://suzannehamner.wordpress.com/2016/11/26/internet-control-now-up-for-grabs-china-battling-heavy-for-internet-control/

Don't forget about NNTP (Usenet). It's not "the internet".

How is there an internet kill switch? Where's the source for that? Wouldn't that be impossible? They'd have to get every ISP to agree, surely?

It's ICANN. There are seven keys needed to reset the internet and 14 in total around the world. Many of the keyholders are unknown. The US branch just went private because of Obama.

From my limited understanding it's a reset for the global dns (ip addresses) in case of emergency. It would essentially bring the internet back to square one. They would probably be able to recover a lot of sites in time but a crazy amount of data would be forgotten and lost.

Yes. A huge part of the population will go crazy if internet access goes away.

Precisely. I came to the same conclusion independently.

The Net Kills Switch works like this :

7 person in the world from different countries (USa / Eu / Asia ) have Master key + password.

You have to connect all 7 keys to engage the killswitch. 7 other person for safety mesure, got a copy of one's key, so 14 in total.

They meet twice a year to destroy old keys and get new ones.

EDIT : Before, it was an american company, but now it's no country-related.
