At least two of the root servers (G-ROOT and L-ROOT) reportedly "suffered badly" while two others (F-ROOT and M-ROOT) "experienced heavy traffic". The latter two servers largely mitigated the damage by distributing requests to other root server instances with anycast addressing. ICANN published a formal analysis shortly after the event. [3] Due ...
DNS TLD Outage: Worldwide: 50,000,000: An Ingres database failure resulted in corrupt .com and .net zones, which were subsequently released to the DNS root servers. As the root servers were reloaded, they began to return failures for all domains in the .com and .net zones. [29] [30] 4 hours: DNS: Automation and Human Failure: InterNIC / Network ...
The DNS root zone is the top-level DNS zone in the hierarchical namespace of the Domain Name System (DNS) of the Internet.. Before October 1, 2016, the root zone had been overseen by the Internet Corporation for Assigned Names and Numbers (ICANN) which delegates the management to a subsidiary acting as the Internet Assigned Numbers Authority (IANA).

A root name server is a name server for the root zone of the Domain Name System (DNS) of the Internet. It directly answers requests for records in the root zone and answers other requests by returning a list of the authoritative name servers for the appropriate top-level domain (TLD).
BIND, the most popular DNS name server (which includes dig), incorporates the newer DNSSEC-bis (DS records) protocol as well as support for NSEC3 records. Unbound is a DNS name server that was written from the ground up to be designed around DNSSEC concepts. mysqlBind, the GPL DNS management software for DNS ASPs, now supports DNSSEC.
During a DNS flood the host that connects to the Internet is disrupted due to an overload of traffic. It can be referred to as a disruption that causes the work of the resource or machine to halt by not allowing the traffic to land on it. This attack is mainly done by hackers [citation needed] to benefit from the attacked resource or machine ...
The IANA-run servers were under increasing load from improperly-configured NAT networks, leaking out reverse DNS queries, also causing unnecessary load on the root servers. The decision was made by a small subset of root server operators to run the reverse delegations; each announcing the network using the autonomous system number of 112. [9]
Major DNS resolvers returning "SERVFAIL" status for Facebook.com. Security experts identified the problem as a Border Gateway Protocol (BGP) withdrawal of the IP address prefixes in which Facebook's Domain Name System (DNS) servers were hosted, making it impossible for users to resolve Facebook and related domain names, and reach services.
