Here’s how to tell if your web traffic travels through an NSA listening point

A Canadian project by Internet Exchange Maps, called IXmaps, tracks the internet exchange points your information passes through. These “points” are buildings where your information passes along a wire and can be collected by the NSA.

For financial and political reasons, many Canadian internet routes pass across the border into the U.S.—a phenomenon known as “boomerang routing”—before going back into Canada to its original destination. Since Canadian citizens have no privacy rights in the U.S., their data is often collected and stored without question.
