I'm a bit surprised at this whole thread. I used to do some internationalization at Google, and the old policy was that cookies always trump geolocation. Maybe there's been changes. Incidentally, Accept-Language was not always respected either, but that was deliberate -- it used to be considered an unreliable signal, especially in some markets where the user's OS was often non-localized or pirated. But I've heard that in these modern times it's more indicative of real user preference.
