Internet Anomalies In Mainland China In 2014
In the afternoon of January 21, 2014, the Chinese internet suffered a major failure. The country's Domain Name Service, DNS infrastructure, which is responsible for translating domain names into IP addresses, started directing unrelated domains from various top-level domain name, TLDs to the completely unresponsive IP address 65.49.2.178 at 15:10 (UTC+8). As a result, two-thirds of all domestic websites became non-functional, including such high-traffic sites as Baidu and Sina Corporation, Sina. It is debated what caused this incident. Chinese officials point to the fact that the IP address is owned by Dynamic Internet Technology, an American Falun Gong-affiliated corporation most known for developing the Great Firewall circumvention tool Freegate, and argue that it was caused by external hacking. Independent researchers, however, argue that the incident is more likely caused by a misconfiguration in Great Firewall's DNS poisoning mechanism. Incident timeline At 09:00 on January ...

Domain Name Service
The Domain Name System (DNS) is a hierarchical and distributed name service that provides a naming system for computers, services, and other resources on the Internet or other Internet Protocol (IP) networks. It associates various information with ''domain names'' (identification strings) assigned to each of the associated entities. Most prominently, it translates readily memorized domain names to the numerical IP addresses needed for locating and identifying computer services and devices with the underlying network protocols. The Domain Name System has been an essential component of the functionality of the Internet since 1985. The Domain Name System delegates the responsibility of assigning domain names and mapping those names to Internet resources by designating authoritative name servers for each domain. Network administrators may delegate authority over subdomains of their allocated name space to other name servers. This mechanism provides distributed and fault-toleran ...

Routing
Routing is the process of selecting a path for traffic in a Network theory, network or between or across multiple networks. Broadly, routing is performed in many types of networks, including circuit-switched networks, such as the public switched telephone network (PSTN), and computer networks, such as the Internet. In packet switching networks, routing is the higher-level decision making that directs network packets from their source toward their destination through intermediate network nodes by specific packet forwarding mechanisms. Packet forwarding is the transit of network packets from one Network interface controller, network interface to another. Intermediate nodes are typically network hardware devices such as Router (computing), routers, gateway (telecommunications), gateways, Firewall (computing), firewalls, or network switch, switches. General-purpose computers also forward packets and perform routing, although they have no specially optimized hardware for the task. T ...

High Availability
High availability (HA) is a characteristic of a system that aims to ensure an agreed level of operational performance, usually uptime, for a higher than normal period. There is now more dependence on these systems as a result of modernization. For example, to carry out their regular daily tasks, hospitals and data centers need their systems to be highly available. Availability refers to the ability of the user to access a service or system, whether to submit new work, update or modify existing work, or retrieve the results of previous work. If a user cannot access the system, it is considered ''unavailable from the user's perspective''. The term '' downtime'' is generally used to refer to describe periods when a system is unavailable. Resilience High availability is a property of network resilience, the ability to "provide and maintain an acceptable level of service in the face of faults and challenges to normal operation." Threats and challenges for services can range from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
