A DNS attack in China crippled Internet access in part of the country, reports Computerworld.
The DDoS attack targeted only DNSPod's DNS servers. Access to the registrar's IP address was blocked as network operators were concerned that the servers were draining resources from the machine rooms they occupied. The issue could have stopped there, but users trying to boot up a video application had their unanswered DNS requests passed on to higher-level servers that didn't know how to process them, resulting in a massive traffic jam.
Internet access returned to normal several hours later, according to The Register.
