> I remember some HN user from Switzerland saying that IIRC either his IP is being moved around in geoIP databases between Swiss regions, or getting slightly distinct IP each time; as a result, he randomly gets all kinds of websites in French, and sometimes in German. Imagine this.

Sometimes my IP resolves close enough to the Röstigraben[^1] that I will get sites in German despite having my browser set to English (GB) and OS set to French.
