The DNS filtering apparatus of China’s Great Firewall (GFW) has evolved considerably over the past two decades. However, most prior studies of China’s DNS filtering were performed over short time periods, leading to unnoticed changes in the GFW’s behavior. In this study, we introduce GFWatch, a large-scale, longitudinal measurement platform capable of testing hundreds of millions of domains daily, enabling continuous monitoring of the GFW’s DNS filtering behavior. We present the results of… Expand
