Let's say you have more fine-grained capacity in a given metro than Cloudflare has in an attempt to provide additional value in that metro than Cloudflare can offer. You are blocked from doing so if endusers are using Cloudflare DNS.

I don't know if this is happening at the moment, but it's pretty clear that there is no real incentive to even attempt this given that you simply will not be able to offer any benefits because you don't have the data.

Who would set up ( or use) a dns that is better in 1 metro in the world? Do you?

The example given doesn't make any sense.

You're just giving an ideological example. Not one that occurs in the real world.

Here is one that actually happens: Using cloudflare DNS to protect privacy is one that occurs in the real world and eg. Apple is using them for exactly that.

But let's repeat:

> We are working with the small number of networks with a higher network/ISP density than Cloudflare (e.g., Netflix, Facebook, Google/YouTube) to come up with an EDNS IP Subnet alternative that gets them the information they need for geolocation targeting without risking user privacy and security.
