"Due to the centralization that is caused by public DNS services, large content delivery networks (CDNs), such as Akamai, are no longer able to rely on the source IP of DNS queries to pinpoint their customers. Therefore, they are also no longer able to provide geobased redirection appropriate for that IP."
I always thought that the go-to way to solve geobased redirection was to make all your PoPs listen to the same IP(s) (I think some BGP is involved here), and let Dijkstra's algorithm let all clients find the shortest path to the nearest PoP? Isn't this exactly what Google and CloudFlare are doing with their own DNS IPs?
