Which of the top 5, 10, 100 sites on the Internet use anycast?

If Facebook, Amazon, Google, Wikipedia, etc., are using standard IPv4
and IPv6 endpoints and are *not* using anycast, and they have
successly fielded defenses against DDOS's without using anycast,
wouldn't that tend to blow a gigantic, gaping hole in your assertion?
