    Which is why I said when. It's perfectly possible for a group of privacy advocates to work collaboratively to create such a thing and host it in countries whose 'security' laws are more reasonable.



    Actually there's no reason an encrypted, P2P search engine could not be developed with no backbone to subpoena.



    EDIT: Looks like such a thing does exist and I think it will get my patronage. http://www.yauba.com

    Appleinsider is one of the few Apple oriented website to offer, most of the time, quality content. That article does not qualify for that category.

    It's like the AI linkbait pulled the Googlians out of the woodwork. This must constitute that 20% where you don't have to work?

    An FAQ can say whatever they want it to say, whatever is expedient, whatever furthers their corporate goals. It's not as if this carries the legal weight of, for example, a sworn deposition by Eric Schmidt.



    How is this any different from an FAQ that says, for instance, that they don't collect and/or index data about or from WiFi access points during their Street View sweeps?

    This makes perfect sense, and is not a 'slam' at Google. Get your feathers down.

    I've been having this problem since I got my AppleTV gen 2, and have been frustrated by 30 hour downloads.

    I've been using Google DNS, and after reading this article, switched back to my default Comcast, and presto, I'm now downloading quickly enough to start viewing movies within 1-2 minutes.

    Staggering difference.



    The issue is not any particular failing with Google or OpenDNS (I wish I could stay with OpenDNS for its parental controls). The fact is the way Akamai works. It identifies the entry closest to the Akamai routers, and if you're giving it some Google DNS server far away from you (in routing terms), then you totally defeat (and actually worsen) the purpose of Akamai.

    Advertise your real DNS location and the system works like a charm.

    Stop fighting, Akamai confirmed they do use DNS lookup as a method to pick what Server you download from.



    I asked on twitter when tuaw posted this news via zdnet.

    I'm guessing that ATV2 somehow has Akamai more baked in, because I agree that I still have my ATV1 running along side my ATV2 and it has been running fine with OpenDNS.

    I haven't had any problems with Google DNS. I'm rather fond of Open DNS myself.



    Correct!!! DNS is a lookup, sure that initial lookup could take a milisecond longer if your local ISP DNS is closer in terms of latency.....but it also could NOT have the info you need and it would have to forward the request or hit a root server. In either case once you have the IP of the media streaming server, DNS is out of the picture.



    Appleinsider ONCE AGAIN showing their NUT JOB bias. Google is a major threat to Apple, therefore and enemy of AI???

    Dilger may work for Apple PR, but is 100% correct in this case. Not using your ISP DNS server can cause exactly the effect described, for exactly the reason described.

    WHOOOSH! The sound of the article going right over your head.

If you don't know what you're public IP address is, look it up on http://www.whatismyip.com.



    It is too late. Once you've connected to the CDN, they can't reconnect you to a closer mirror in most cases. The DNS lookup is their chance to steer you the right way. In some cases, they can fine tune it within the routing tables, but the DNS lookup is a biggie.

    My ISP has an Akamai server farm in their building, and they say in order to benefit from it we must use their DNS. So I think it can matter what DNS you use. The DNS takes a name and sends an IP address back, and certain ISPs will change their DNS to send back IP addresses of computers they know are nearby.

Other posters are right, though, this is not specifically a Google problem, it's also a problem with OpenDNS and other commonly used alternatives to your ISP's DNS server. In our high-bandwidth world where geolocation is key, when you give up your ISP's regional DNS for an external server that may be far away, you're going to see this issue.



    Thanks!!! Most of the fast responders missed the ball! Some people still think the world ends at their doorstep!

    It depends how well openDNS/googleDNS match the preference of Akmai...



    That means for those whom dont get it:



    - Use ISP DNS = works allways.

    - Use openDNS/googleDNS = it works or it doesnt work, it dependson things.



    But Akmai might make this work better but dont hold your breath...

    Yes its true there are a lot of nutjobs that dont see the whole picture like you in this case. They allways assume that the do but that is seldom the case.



    To mee it doesnt look like it would be impossible for akmai to optimise for all but its up to them... There are allways going to be things that screw up things like these eg. proxys and so on. To Akmai its important that 99,5% of customers are happy and the rest get screwd, not many people will fool around with dns servers anyhow...

    As for for not trusting the UK with data, that would be rather funny if you are US based. The NSA monitor everything, whether legally entitled to or not.

    Yes, they're using DNS. Trouble is, they're using THEIRS rather than YOURS. In other words, whatever you are using is not going to change what they use or, to rephrase that, changing DNS is not going to assign you a different IP address (or location).

    Sorry, the tin hat conspiracy theory crap about Google gets old. And so do the stupid attacks on anyone who has anything vaguely positive about anything not from Apple.

    Love these threads.



    This is very plausible, why......?



    Because even though DNS server do just translate name to addresses (and reverse), what DNS's like OpenDNS and Google DNS do not do is house the records in an authoritive way.



    So why does switching DNS from Google to a local provider based one work?



    Because CDN's like Akamai switch authoritative responses for domain addresses based on DNS lookups of the whois record (which contains total physical address information) to local information caches. These records have way more accurate/consistent physical location information then an IP trace (which I believe is still used in the event an address cannot be found appropriately).



    DNS flow diagram



    Request:

    User request -> DNS -> lookup for root domain on root servers -> authoritative domain server



    Reply:

    Authoritative domain server -> DNS -> user



    This isnt how Akamai always routes, I believe they prefer client information directly when possible, but as browsers lock down and hardware devices are hardened, its very difficult sometimes. This also is only a single layer of how they try to route content locally.

    FTA: "CDNs like Akamai, which Apple works with to deliver iTunes downloads, use DNS lookup information to locate where users are, and then optimize content delivery via the nearest available server."



    When you use a central DNS, Vs one near your home, Akmai ends up using a server to deliver to you that is less than ideal, sometimes by thousands of miles.



    Further more... he wrote DNS service like Google and Open DNS and the other one... Not JUST Google... he's not singling them out or stearing away from others... he specifically wrote central DNS servers, as opposed to your local one. And he does say that the Google like ones can speed up your service-- just not if your heavy content is poorly routed. Re-read the article and drop your overly defensiveness to see what he ACTUALLY wrote.



    and how does akamai know which DNS server you resolved from? the location is done via reverse IP lookup where they take your IP address. this is done on akamai's side via their DNS infrastructure



    the reason people use google DNS is that it's always up and it's fast. ISP DNS servers are like bastard step children where they put them on the oldest hardware they have lying around at the time



    DNS lookups and content routing are two different things



    i'm not a DNS expert but unless Google is poisoning their results and sending you to the wrong servers i don't see how a DNS lookup is a slow down issue. it could be the way akamai has their server IP's assigned for load balancing and Google DNS is screwing it up

    Google is not poisoning, Akamai is....



    When the DNS resolver from google goes and looks for the root server, Akamai authoratative host reverses on the Google DNS server because client IP is not passed through, only the originating DNS request client IP is passed though. In this case google DNS acts as a proxy. Google and Cisco were looking at extending DNS requests to include client IP for CDN's as part of the original DNS request, not sure where they ever got with that.



    That being said, the theoretical absolute optimal way (given a good IP lookup and a couple other factors) to get on the best CDN cache to you would be to set your computer to use Akamai DNS directly. This is offset by things like ISPs putting content caches inside their networks. One that comes to mind is Comcast. In that case they do return a comcast server which may not be geographically optimal to you but which may in fact return much greater throughput and/or reduce data charges.
