Anycast Routing is used on the Internet to provide many services, including NTP and DNS, but very few know that you can locally deliver websites and content over HTTP/TCP/Anycast. There's many factors that go into designing an anycasted network.

We'll also depict how live DDoS attacks are contained to their source region based upon anycast routing. (success).
