Which method are they using?

  Well, it can’t be the JavaScript location API, because there’s no JavaScript on that page, and anyway my browser would ask me if the page wanted to use my location. The only other method I know of that relies on information the site could get just by my visiting the page is looking the IP address up in a database of IP addresses and locations.

  Gonna guess Geo IP lookup.

  GeoIP (IP-to-location database). http://status.wikimedia.org/8777/156490/GeoIP-lookup http://status.wikimedia.org/8777/156490/GeoIP-lookup

  Unless it's changed recently (I haven't followed the discussion since last year) it's using the free version of the MaxMind IP->city database (http://www.maxmind.com/app/geolitecity http://www.maxmind.com/app/geolitecity). I can't seem to find the relevant mailing list threads, but here's some evidence of ad-hoc accuracy testing last August: http://meta.wikimedia.org/wiki/MaxMindCityTesting http://meta.wikimedia.org/wiki/MaxMindCityTesting
