<div class="WordSection1">
<p class="MsoNormal">When you send a DNS query to 8.8.8.8 it goes to the “nearest” resolver. Not nearest in terms of location since 8.8.8.8 is an anycast address and exists in many locations. It’s the BGP path to 8.8.8.8 that determines nearest. Next, the resolver
 does it’s thing and sends a query to the akamai DNS. That DNS is probably also an anycast address so again, how close is it? Akamai then tries to geo locate you but they have the IP of Google, not you. You get an IP and connect to that. Everything up till
 now probably doesn’t matter as it’s probably not the DNS that is causing what you see. The IP is not Nike but rather an akamai proxy. When you connect to akamai proxy, the proxy can see your IP and may do the Geo location lookup and pass what it thinks as
 your location to the content server. When it gets to the content server, it may use that Geo information but possibly not. It’s likely it’s not the content server but a load balancer. In either case, they may ignore any Geo lookup done by akamai and try to
 locate the incoming IP. Well, that’s actually the address of the akamai proxy. Hopefully the developers thought of this and had akamai pass your IP in a header and geo locate on that. It’s probably the content server that is sending an HTTP redirect to get
 you to the “/ca” location on the site.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So there can be as many as 4 different times you are being geo-located. Which on actually matters is difficult to tell. Assuming Nike did a good job, it’s probably the Akamai proxy going the geo-locate and the code on the content server
 is consuming that and redirecting you to the location specific part of the site.<o:p></o:p></p>
