We never had any official statement for people putting mirror behind CDN, as we also use for some services CDNs providers (AWS and CDN77 are sponsoring the project as one example). But as you saw in previous answers, you should probably verify first that it wouldn't be a problem with your CDN (cloudflare here) provider. Second thing : as said too, we redirect traffic ourselves (through mirrorlist.centos.org) by using GeoIP at the origin IP level, and compare that with our lists, including for USA at the state level (for efficiency). I don't think you mentioned the State your mirror would be in, but in fact that means that we'd be hitting cloudflare, so don't even know if in that case people would still be redirected to correct state, or instead other PoP in their network.
