“There’s been sudden interest recently in a Chinese route hijacking incident that occurred way back in April, brought about by a new report to the US Congress that highlighted the event (see pages 236-247). A second Chinese event, also in the report, has received almost no attention despite being much more interesting (technically, anyway). A Chinese DNS censorship incident occurred just one month earlier, in March, and although we already presented an analysis of that event (here and here), today we’ll provide an update on the incident and its scope. But first, let’s step back and get some context on events such as these, and see if the hype is warranted.”
