The Great Firewall ( GFW ; simplified Chinese : 防火长城 ; traditional Chinese : 防火長城 ; pinyin : Fánghuǒ Chángchéng ) is the combination of legislative actions and technologies enforced by the People's Republic of China to regulate the Internet domestically. Its role in internet censorship in China is to block access to selected foreign websites and to slow down cross-border internet traffic. The Great Firewall operates by checking transmission control protocol (TCP) packets for keywords or sensitive words. If the keywords or sensitive words appear in the TCP packets, access will be closed. If one link is closed, more links from the same machine will be blocked by the Great Firewall. The effect includes: limiting access to foreign information sources, blocking foreign internet tools (e.g. Google Search , Facebook , Twitter , Misplaced Pages , and others) and mobile apps, and requiring foreign companies to adapt to domestic regulations.
90-645: Besides censorship, the Great Firewall has also influenced the development of China's internal internet economy by giving preference to domestic companies and reducing the effectiveness of products from foreign internet companies. The techniques deployed by the Chinese government to maintain control of the Great Firewall can include modifying search results for terms, such as they did following Ai Weiwei ’s arrest, and petitioning global conglomerates to remove content, as happened when they petitioned Apple to remove

270-866: A root name server run by Netnod in China started returning poisoned DNS results to global users, preventing users in Chile and the U.S. from accessing sites such as Facebook. The server was shut down to stop the poisoning. In 2014, two-thirds of China's DNS infrastructure began resolving unrelated domains to 65.49.2.178, an address owned by the US-based Dynamic Internet Technology, Inc. , resulting in widespread internet outage in China . No damage to DIT services were reported despite what amounts to an accidental DDoS . While some sources attribute this incident to GFW's DNS poisoning, others (mostly quoting Chinese sources) speculate this incident

Michael Sheridan of The Australian suggested that Ai had offered himself to the authorities on a platter with some of his provocative art, particularly photographs of himself nude with only a toy alpaca hiding his modesty – with a caption『草泥马挡中央』 (" grass mud horse covering the middle"). The term possesses a double meaning in Chinese: one possible interpretation
450-874: A 20 September 2000 document from the Chinese State Council , posted by the Xinhua News Agency, lists 9 categories of information which should be censored , blocked, or filtered from access to the citizens using the internet within China: To filter this content, the Chinese government not only uses its own blocking methods, but also heavily relies on internet companies, such as ISPs, social media operators such as Weibo, and others to actively censor their users. This results in private companies censoring their own platform for filtered content, forcing Chinese internet users to use websites not hosted in China to access this information. Much of this information

State media also reports that Ai was granted bail on account of Ai's "good attitude in confessing his crimes", willingness to pay back taxes, and his chronic illnesses. According to the Chinese Foreign Ministry, he was prohibited from leaving Beijing without permission for one year. Ai's supporters widely viewed his detention as retaliation for his vocal criticism of

Analysts and other activists said Ai had been widely thought to be untouchable, but Nicholas Bequelin from Human Rights Watch suggested that his arrest was calculated to send a message that no one is immune and that the arrest must have had the approval of someone in the top leadership. International governments, human rights groups and art institutions, among others, called for Ai's release, while Chinese officials did not notify Ai's family of his whereabouts. State media started describing Ai as

The internet in China arrived in 1994, as
2160-471: Is related to sensitive topics. The Great Firewall's goal is perceived by the Chinese Communist Party as helping to protect the Chinese population by preventing users from accessing these foreign websites which, in their opinion, host content which would be 'spiritual pollution', as well as information about these sensitive topics. These topics include: A 2020 study found that the Great Firewall blocks approximately 311,000 domains. The Cybersecurity Law behind

Crandall and others argued that the main purpose is not to block 100%, but rather to flag and to warn, in order to encourage self-censorship. An illustrative but incomplete list of tactics includes: Because of the complexity involved in maintaining

The definition also includes using the internet to distribute information considered "harmful to national security," and using the internet to distribute information considered "harmful to public order, social stability, and Chinese morality." The central government relies heavily on its State Council regulators to determine what specific online behavior and speech fall under these definitions. The reasons behind

The group disbanded in 1983, yet Ai participated in regular Stars group shows, The Stars: Ten Years, 1989 (Hanart Gallery, Hong Kong and Taipei), and
2700-483: The CAC is also using active probing in order to identify and block network services that would help escaping the firewall. Multiple services such as Tor or VPN providers reported receiving unsolicited TCP/IP connections shortly after legitimate use, for the purported purpose of network enumeration of services, in particular TLS / SSL and Tor services, with the aim of facilitating IP blocking. For example, shortly after

4230-498: The Internet is one of " Internet sovereignty ": the notion that the Internet inside the country is part of the country's sovereignty and should be governed by the country. While the United States and several other western countries passed laws creating computer crimes beginning in the 1970s, China had no such legislation until 1997. That year, China's sole legislative body – the National People's Congress (NPC) – passed CL97,

Users are prohibited from using the Internet to create, replicate, retrieve, or transmit information that incites resistance to the PRC Constitution , laws, or administrative regulations; promoting the overthrow of the government or socialist system; undermining national unification; distorting
4410-719: The NPC claimed that it intentionally left the law "flexible" so that it could be open to future interpretation and development. Given the gaps in the law, the central government of China relies heavily on its administrative body, the State Council , to determine what falls under the definitions, and their determinations are not required to go through the NPC legislative process. As a result, the Chinese Communist Party has ended up relying heavily on state regulation to carry out CL97. The latter definition of online activities punishable under CL97, or "crimes carried out over computer networks",

Despite this, there have been growing criticisms that the actions of the Chinese government have only hurt Chinese free speech, due to increased censorship, and lack of non-sanctioned sources of information, such as Misplaced Pages and many English news sources. This has resulted in reports of some cases of legal persecution of those charged with spreading this information. The Chinese government itself does legally support free speech; article 35 of

While the Great Firewall has had an impact on Chinese citizens' ability to use the internet to find information about sensitive topics about the Chinese Communist Party, it has not completely stopped them from doing so.

Gradually, while Internet availability has been increasing, the Internet has become a common communication platform and tool for trading information. The Ministry of Public Security took initial steps to control Internet use in 1997, when it issued comprehensive regulations governing its use. The key sections, Articles 4–6, are: Individuals are prohibited from using
6030-864: The international internet. Because the Great Firewall blocks destination IP addresses and domain names and inspects the data being sent or received, a basic censorship circumvention strategy is to use proxy nodes and encrypt the data. Bypassing the firewall is known as fānqiáng (翻墙, "climb over the wall"), and most circumvention tools combine these two mechanisms: In 2017, the Chinese government declared unauthorized VPN services illegal, requiring VPN providers to obtain state approval. Although China restricts VPNs, they remain widely used by private individuals. State-owned enterprises or state institutions also use VPNs for official work. The Chinese government has authorized several official VPN providers. Those who develop or sell their own VPNs potentially face years in prison. Non-proxy circumvention strategies include: In 2010,
