We find that Flickr and OneDrive remain consistently blocked, but LINE and KakaoTalk show inconsistent fluctuation between accessibility and inaccessibility. We also analyze security and privacy of FireChat and test accessibility of the service in China.

LINE and KakaoTalk Disruptions in China
In this post we examine how the Great Firewall of China is implementing DNS tampering and HTTP request filtering on KakaoTalk and LINE domains, which is disrupting service of the applications as a result. We find that Flickr and OneDrive are also blocked through DNS tampering. We also analyze recent changes to the LINE keyword filtering list.
