It's a good question. Historically we've advocated against it primarily because we can't fix DNS performance issues related to infrastructure we don't control/own. If your any cast resolver sends you to a CDN point in Hong Kong instead of one in Sydney with 100ms extra latency… the provider is powerless to stop it. We've seen this issue with 8.8.8.8 before; and often are "fixing' performance issues for customers by changing their resolvers back to our own internal ones. This one seems really fast, and quite reasonable in terms of results. I guess CloudFlare have been pretty good at that for quite some time. Will be interesting to see what happens with this though.
