How apropos that you asked this today when Paul Vixie wrote an article just to address this very topic.http://queue.acm.org/detail.cfm?id=1647302 In my experience, solving this problem turns out to be exceptionally difficult. My few naive attempts at it have not been shining examples. Anycast is pretty cool, but works best (exclusively?) with stateless protocols such as DNS. Corey
Yes, anycast does much better with stateless. I was meaning to use the anycast to answer your dns from the closest (online) geographical point, whcih would answer with it's local http service (non-anycast). If the closest data center were offline, the next closest anycast DNS would answer with it's own http farm.
