Dear Stefan
One possible source of that problem could be outdated databases of a geolocation service provider.
There are some commercial providers (e.g. ip2location.com) which offer geolocation of IPs as a serivce. This makes sense sometimes, when e.g. a network spans multiple regions and/or countries and you still want to know, where a specific IP is located. Those service providers do not only rely on the public IP databases such as RIPE, but also on other information (probably confidential, how they exactly do it). The downside is, that they do plausibilty checks and it might be, that it seems unplausible to them, that a german customers has a Swiss upstream...?
Only one of a gazillion possible reasons...
Kind regards, Viktor

hello everybody
Is anybody of you aware, how the most popular services (Google, Zattoo, Facebook, etc) are matching geographic locations to ip-adresses ?
Our AS (41666) is located in CH, so also all the ripe objects are registered with country-code CH.
Now we have a customer located in Germany, so I created a inetnum-block with his subnet in ripe-db with country-code DE. This was a week ago. The customer is still complaining that he is constantly redirected to the swiss-versions of all the services.
Does anybody of you experienced a similar problem ? Does anybody knows proper solution ?
Thanks for any advice in advance
Best regards
Stefan Renner
