Umbrella utilizes anycast routing. When you configure your network to send traffic to the Umbrella servers, your traffic could be routed through any of the locations listed on our System Status page, depending on geographical distance, peering, congestion, and other measures.
Some websites and content delivery networks provide different results based on the IP-Geolocation they detect for the user. Using Umbrella can affect the geo-location results you receive. The behaviour encountered will depend primarily on the Umbrella Data Center location that the traffic arrives from. As a result, some websites may not display pages that match where the user is located geographically (for example, a user in Italy maybe routed to our Frankfurt datacenter, resulting in websites displaying in German instead of Italian).
Umbrella now supports Geo-location for Google and servers, honoring XFF to present the web pages in local language. The geo-location for Google is available using PAC, Proxy chaining and AnyConnect. This will allow any site honoring XFF headers for Geo-location to serve appropriate localized page. HTTPS decryption is mandatory for this new feature to function properly.
