Are seven keys able to turn off the internet?
I had recently researched the possibility of turning off the internet, and found an explanation in another forum: How to take down the internet?
The distributed nature of the internet makes it really impossible to destroy all of it, and all the information on it, without destroying every computer as well, which you seem to be excluding. To erase all access everywhere you must contact every computer on the internet.
What these men and women control is the system at the heart of the web: the domain name system, or DNS. This is the internet's version of a telephone directory – a series of registers linking web addresses to a series of numbers, called IP addresses. Without these addresses, you would need to know a long sequence of numbers for every site you wanted to visit. To get to the Guardian, for instance, you'd have to enter "18.104.22.168" instead of theguardian.com.
I really wanted to know if the 7 keys really can have this possibility. To me this sounds a lot like fiction
