We run our own dns servers mostly because some sites look at where the dns query is coming from and depending on that return results that are local.
E.g. Facebook. If you resolve using google’s dns the Facebook traffic goes via international however if you resolve off our dns servers it goes via peering in nsw and is a lot faster.

How many operators promote services like 1.1.1.1 and 8.8.8.8 to their customers instead of operating their own recursive DNS infrastructure? And if you do, what was the driver and then risk mitigation position taken? 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.
