All this talk about redundancy, real-time apps, scalable architecture and and a "simple" DDOS against DNS architecture brings half of the internet down. Honestly did nobody think about having a spare dns at some other company? or even backup dns server exactly for a situation like that?

This is going to be a fun day. This little DNS outage is likely to cause millions of lost revenue for many industries. Im dead in the water and I cant complain on twitter :-(

change your name server at your registrar to something else, add all necessary entries in the new DNS and be up before DDoS is stopped.

Sadly we're too interconnected. Every company that relies on that DNS should do what you suggest, but the control is definitely not in our ( users ) hands.

The TTL for the glue records of a .com domain is 48 hours, so even if you have Route53 set up and ready to go, it takes a long time to switch the zone away from Dyn.

We switched from Dyn to Rout53 a few weeks ago. It took about 12 hours before half of the traffic had shifted over.

From where I'm looking at the internet (central Europe), I don't notice anything.

Maybe your internet on the other side of the Atlantic is broken, ours seems to be working fine. ;-)

Edit: Looks like the eastern part of the USA is affected: https://cloudharmony.com/status-for-dyn
