    Hey OpenDNS peeps,

    I'm involved in a discussion at Amazon's AWS developer forum, regarding traceroutes not going to the closest Cloudfront location when using OpenDNS as your DNS resolver.

    Please see here:
    http://developer.amazonwebservices.com/connect/thread.jspa?messageID=108338

    In a nutshell: I'm in NYC, and get routed to OpenDNS resolvers in NYC, but when tracing a route to Cloudfront, I am consistently routed to San Jose (Palo Alto).

    Hopefully by brining this to your attention we can get this figured out soon, unless Amazon has already contacted you guys and/or your ISPs.

    Thanks!
    -Dan

    If you use your ISP's DNS servers, is this then any different? Probably not! Only under rare circumstances OpenDNS may return a different IP address than your ISP. Also tracing a route is almost not related to DNS, but to the routes set up by your ISP. Therefore I believe that OpenDNS is out of the game here.

    I'm having a similar problem. We use OpenDNS on our office network in Guangzhou, China and consistently get served by CDNs (including Cloudfront) from west coast usa instead of Hong Kong edge servers. If I switch to our ISP's (China Netcom) DNS servers I get served from Hong Kong or Japan.

    CDNs that use anycast (like cachefly) don't seem to have this problem.

    Is this always going to be a problem until OpenDNS has servers in the region?

    We are working with Amazon to correct this issue. Expect to see better results within the next few days.
