we're located in australia and i recently noticed downloads from microsoft taking an excessive amount of time. upon investigation i realised that microsoft and akamai were directing us to a U.S. download site because they believed that's where we were.

i disabled opendns and the download came from an akamai server located just a few hops away at a local ISP.

in order to get around the problem with microsoft, i've had to modify my bind nameserver configuration and specified 6 domains to be looked up directly and not via opendns.

while this solves my problem with microsoft, i'm sure there are heaps of other caching networks that are going to have to be manually listed in the same fashion.

perhaps opendns could recognise this and spoof the dns lookup request to these sites with my original IP address. this would ensure I get the best result.

I can't see any way of OpenDNS spoofing your IP address.

This is a real issue which I have also experienced

I've also had to kludge Bind too!

If any staff at OpenDNS have an answer to this I'd be very interested.....

I am not OpenDNS staff but I guess what happens is the following: You make a request to your DNS server. The DNS server does a recursive query that ends up with akamai. Akamai serves a different IP depending on the location of the DNS server. So if your DNS server is in the US, Akamai will give you an US download server.

I think you'd be better of requesting OpenDNS put servers in Australia. The addition of the London servers dropped these comments from users in Europe. I am seeing more and more posts from the South Pacific, looks like your turn will be brain stormed soon.

Oh please, A South Pacific server would be an answer, but it still raises problems, I have customers in NZ who used OpenDNS and enjoyed it, but we had to drop it due to the direction of updates from the states. Ex NZ bandwidth was chargeable whilst internal was not, MS updates and Adobe being the biggest. So pointing to servers in Oz, still would not solve the problem for us in NZ.
