Not ideal for performance too, sites/APIs with regional endpoints could then be slower. Understand the privacy impact, could CloudFlare client “anonymize” edns subnet by region-ing the request based on large cloud regions? (rather than actual client subnet)

Site should load just fine without eDNS -- even "geo-specific" ones. They will just route you as if you came from your local Cloudflare PoP rather than your home IP; usually not a big difference since Cloudflare is in so many locations. I'm not having any trouble with bbc.co.uk on 1.1.1.1, maybe it was a temporary hiccup. (Disclosure: I work for Cloudflare but not on this product.)

    Ouch. Do you know which PoP (point of presence) you're hitting? To find out, Look at the last three letters in the CF-Ray header on any response from a Cloudflare site, e.g. curl -v cloudflare.com 2>&1 | grep -i CF-Ray The letters should correspond to an airport code nearby the CF server you landed on. Let me know what it says.

      CF-RAY: 4c0c98839feb5ff3-MRS Its hitting the Marseille, France POP. I posted the issue (bad route) on the community forum a few months ago. https://community.cloudflare.com/t/high-ping-sri-lanka/15276/5 https://community.cloudflare.com/t/high-ping-sri-lanka/15276...

        OK, so it seems like Cloudflare in general is not serving your ISP very well for some reason. :( Hopefully our network team will be able to look into it.

  It was intermittent. Sometimes it worked, sometimes it didn't. The error message given suggested it was trying and failing to find a cloudflare hosted site (which to my knowledge the BBC isn't). Unfortunately I can't remember exactly what the error said. I'll try it again for awhile and see if I have any issues now.

just to clarify, CF doesn't support eDNS client subnet - eDNS is implemented.

This is factually inaccurate. Cloudflare do not use the EDNS Client Subnet extension: https://tools.ietf.org/html/rfc7871 https://tools.ietf.org/html/rfc7871 You are right to say that can potentially affect geo-located services. But that is not to say that 1.1.1.1 doesn’t support EDNS: https://tools.ietf.org/html/rfc6891 https://tools.ietf.org/html/rfc6891
