The DNS Backbone DDoS Attacks have been several significant Internet events in which distributed denial of service attacks (DDoS) have targeted one or more of the thirteen DNS root servers. These attacks are extremely significant, as the root nameservers function as the Internet backbone, translating text-based Internet hostnames into IP addresses. As the nameservers provide this service for DNS lookups worldwide, attacks against the root nameservers are attempts to disable the Internet itself, rather than specific websites. The Internet is the worldwide, publicly accessible network of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP). ...
A denial-of-service attack (also, DoS attack) is an attack on a computer system or network that causes a loss of service to users, typically the loss of network connectivity and services by consuming the bandwidth of the victim network or overloading the computational resources of the victim system. ...

This event was the first significant attack directed at trying to disable the Internet itself, instead of specific websites. The largest malfunction of the DNS servers before this event were seven machines in July 1997, due to a technical problem.
February 6, 2007 A second attack occurred on February 6, 2007. The attack began at 10:30 UTC, and lasted about five hours. Although none of the servers crashed, two of the root servers reportedly "suffered badly", while others saw "heavy traffic". The botnet responsible for the attack has reportedly been traced to South Korea. [1] February 6 is the 37th day of the year in the Gregorian Calendar. ...

On February 8, 2007 it was announced by Network World that "If the United States found itself under a major cyberattack aimed at undermining the nation’s critical information infrastructure, the Department of Defense is prepared, based on the authority of the president, to launch a cyber counterattack or an actual bombing of an attack source." This is likely due to one of the DNS root servers being under the control of the United States Department of Defense.
