Despite the pervasive and continually evolving nature of Internet censorship, measurements remain comparatively sparse. Understanding the scope, scale, and evolution of Internet censorship requires global measurements, performed at regular intervals. We developed Iris, a scalable, accurate, and ethical method to continually measure global manipulation of DNS resolutions. Iris reveals widespread DNS manipulation of many domain names across numerous countries worldwide.
