U.S. Ring Fencing in Umbrella’s Secure Web Gateway (SWG) ensures that traffic for U.S. customers stays within the U.S. This functionality minimizes the possibility of U.S. traffic crossing the Canadian border based on geographic location.
Our Canadian DCs are configured to do a Geo-IP check when a customer looks up the proxy address: swg-url-proxy-https.sigproxy.qq.opendns.com.If the customer IP is detected to be located in the U.S., the traffic will be redirected to a U.S. data center.
U.S. Ring Fencing currently only applies to our Canadian data centers. This means, based on availability, if U.S. customer traffic hits Vancouver, the traffic will be redirected to LAX, DFW, or PAO in order of availability. If U.S. customer traffic hits Toronto, the traffic will be redirected to CHI, NYC, or MIA in order of availability.
