Surge 2010 ~ Anycast Routing: Local Delivery

Posted in Networking, Conferences on February 22, 2012



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 discuss a real world event on Dyn Inc's network which caused a severe service degradation for one of our nameservers due to uncontrolled anycast route propagation, where global traffic landed in our Tokyo datacenter. (failure)

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