geolocation is hard :(

If you would like to see how Google has your geolocation set, check:
curl http://redirector.c.youtube.com/report_mapping

You might want to force it both IPv4 and IPv6 to see if there is any difference.


And run it a few times, because it may think your IP in asia is in Amsterdam, etc..

[jared@eng0 ~]$ curl -4 http://redirector.c.youtube.com/report_mapping
203.105.73.114 => ams09x03 : superx_isp_number: 8 (203.105.64.0/20) [s]
[jared@eng0 ~]$ curl -4 http://redirector.c.youtube.com/report_mapping
203.105.73.114 => sjc07x04 : superx_isp_number: 1 (203.105.64.0/20) [u]

Maybe its actually telling you where youtube is serving videos from for that IP address, in realtime, based on a large number of variables only one of which is where on the Earth that IP might be located.
