Can anyone explain what Anycast is/why it is so huge now? I just looked at the Wikipedia article and it is quite Computer Science-y rather than talking in specific terms how it works or what the benefits are. I understand how DNS works. UDP packet to server, returns IP from host via UDP, and or requests DNS record from a different DNS server with more information about the domain (all the way up to the root servers).
