1. Not sure what you're asking

What do you mean by the "net"? And what do you have in mind as a service? Anything is technically possible, though a lot is unlikely.

2. having the dark web, I don't know if it's existence depends on a functioning internet

that we and everyone uses.
that is, powered and complete but disabled, no traffic at all

It's like a house behind a very long driveway.

7. You had better know exactly what you're doing..

It's rough down there. Anonymity and security in the strictest terms. Porn police and fbi everywhere. Don't buy anything. Just look until you vomit and don't expect to unsee anything. You are warned.

6. An attack on root DNS servers could probably cause that kind of havoc

Lower level attacks are very difficult to do on a mega scale. There's a lot more decentralized routing going on than 20 years ago (when there were like 5-6 central hubs).

will have local DNS servers with everything they need cached. That would probably last long enough for the attack to be mitigated.

8. Geographic regions could be cut off from one another by attacking communications infrastructure

But I believe that what you suggest could be accomplished by our government, but our current administration has not proved itself capable of keeping sharpies away from Twitler, much less this sort of internal coup d'etat.
