How to update IPv6 geolocation data? Google sites blocked.

Hello, and Season's Greetings! We recently lit up a new IPv6-connected location and expanded our ARIN-allocated /48 network to a /44 network to accommodate the additional location (and future locations). However, since moving our small satellite office off our primary /48 and onto their own /48 as part of our /44 network, the users at that office are receiving messages from e.g. YouTube that the "user has not made this content available in your country". How does one go about updating this v6 geolocation data? This is impacting a bunch of our users. Thanks! -David
