Anycast: Useless? DNS or BGP?
I've been toying around with the idea of using anycast DNS to host geographically distributed network of servers for faster speed.
I'm using two of HostHatch's test IPs, one in Los Angeles and one in Oslo:
As you can see, routing is insane... Some east coast locations are routed to Oslo, while sometimes Europe locations are routed to Los Angeles! After averaging out everything, I figure there's practically no benefit to using Anycast DNS.
So, it seems anycast DNS is out of the question.
That leads me to my next question: are anycast IPs any better? E.g. I have HostHatch announce the same IPs in multiple locations.
Or, will that end up being useless like anycast DNS?
Alternatively, I can just use AWS Route 53 with geographic routing or CloudFlare load balancers and call it a day, but I'm curious
What are your thoughts?
