Unknown launched a large-scale DDoS attacks on the servers that hold the top-level addresses of the global Internet. The attack was made by strangers in the 13 servers that are the root of the global Internet, because in them is the matching of top-level domain name [.com, .org, .net and those relating to specific countries] with the IP addresses of websites .

According to a report from root-servers.org, The first barrage took place on Monday, November 30, and lasted for about two hours and 40 minutes. The second one happened a day later and lasted for almost exactly an hour. Most but not all of the 13 root servers that form the Internet's DNS root zone were hit. The attacks started and stopped on their own and consisted of billions of valid queries for just two undisclosed domain names, one for each incident. There's no indication of who or what was behind the attack.

Users encountered the problem as a timeout in their applications to their servers.
The attack took place between November 30 and December 1.
