Well, a large portion of it anyway. A DDoS attack on one domain server created a cascade reaction that left five provinces struggling to get online:
This is what happened during the DNSPod incident, however, it triggered a chain of unexpected events, which led to network congestions for the carrier networks. DNSPod’s servers happen to be used by Baofeng, a highly popular Chinese video streaming service. Once the millions Baofeng users fired up their desktop application, all the requests bounced off on the ISP servers, which did not know how to process them.
The intense traffic on the high-level servers caused bottlenecks, slowing everyone’s Internet connection down to a crawl. In addition to the users in the five aforementioned provinces, who were severely affected, customers in Henan, Anhui and Gansu have also reportedly experienced problems.
