Statistics relating to the number of internet users in Iran are inconsistent and highly disputed, even among Iranian officials. The single official source of data is the ITU, which receives statistics from the government on different information and communications technology (ICT) indicators. According to official sources, the Iranian government calculates the number of internet users by forecasting the number of potential users based on the available bandwidth. Therefore, the reported numbers do not correspond to the actual number of Internet users at all. According to a survey conducted in 2009 by Iran Statistics Centre and published in March 2010, the internet penetration rate in Iran stood at percent; 30 percent of the internet users were based in Tehran; and the penetration rate was Country ProfileIran, OpenNet Initiative, June 16, 2009, http://opennet.net/research/profiles/iran.

IRAN FREEDOM HOUSE Freedom on the Net 15 percent in urban and 3 percent in rural areas. This is significantly lower than the internet penetration reported to the ITU the same year, which was approximately 38 percent.

The internet and its users played an important role in the opposition movement following the June 2009 presidential election, in which incumbent Mahmoud Ahmadinejad was accused of winning a new term through fraud. After the authorities barred international media from directly covering the opposition protests and ensuing violence by security forces, foreign outlets came to rely on user-generated content posted on the internet from inside Iran. The regime characterized these interactions between protesters, internet users, and international media as a soft war orchestrated by foreign powers, and vowed to combat it in kind. The government has reportedly allocated $500 million in its 2010annual budget for this purpose.

During the protests, authorities curbed internet access by introducing 60 to percent packet loss into the network, resulting in a massive drop in speed.3 This came in the context of an existing 128-kilobyte bandwidth limitation imposed on private broadband users beginning in 2006.4 By March 2009, there were only around 557,857 broadband subscribers in Iran, the majority of private users are connected with 56kb to the internet.Given these obstacles, it became difficult to conduct basic online activities like opening email messages or viewing simple webpages.6 The government blamed the slowdown on damage to undersea cables in the Persian Gulf, but the timing was very much aligned with key protests, which strongly suggests that the authorities were in full control of internet speed. Similarly, during protest days many of the important network ports used by instantmessaging and chat platforms were also tampered with, resulting in partial or complete loss of function for these tools.

As of December 2010, all the major international social-networking and mediasharing websites like Facebook, YouTube, and Flickr were blocked, while some file types, such as MP3 audio files, have been sporadically filtered. The periodic filtering and disruption of services based overseassuch as Googles fairly well-encrypted e-mail and blogging platforms, Gmail and blogger.comappear designed to frustrate users and eventually force them to seek more easily monitored alternatives based in Iran. Although many Iranians have been able to access the blocked platforms and content by using various circumvention techniques, the authorities have actively worked to disrupt such efforts, forcing users to constantly adapt and search for new solutions.

According to official statistics, there are approximately 54 million mobile-phone subscriptions in Iran. Mobile-telephone service was also subject to government controls.

Packet loss occurs when one or more packets of data traveling across a computer network fail to reach their destination.

IRAN FREEDOM HOUSE Freedom on the Net Mobile-phone text messaging, or short-message service (SMS), was shut down throughout Iran the day before the election and did not resume until 40 days later. Subsequently it was disrupted on a temporary basis immediately before and during key protests days. There have been reports that messages with banned keywords were filtered even when service was up.

However, any use of SMS by dissenters in Iran is very limited and highly risky. Users must present some form of identification when purchasing mobile-phone subscriptions, making it an easy task for the authorities to track down the authors and recipients of specific messages.

The period after the election featured a broad assertion of power by the Islamic Revolutionary Guards Corps (IRGC), a politically important branch of the security forces that also controls large sections of the economy. Even as it managed the governments crackdown in the streets, it used its economic muscle to increase state dominance of the information landscape. In September 2009, for example, the IRGC purchased a controlling stake in the Telecommunication Company of Iran (TCI), the countrys main provider of internet and mobile-telephone service. The second mobile operator, IranCell, is owned in part by a web of proxy companies controlled by the IRGC (there are a number of high profile IRGC ex-commanders among its management). The third operator, due to be launched in early 2011, is a government-owned entity.

LIMITS ON CONTENT Internet filtering, which began toward the end of the Khatami presidency in 2005, has become more severe since the June 2009 election. The authorities now employ a centralized filtering system that can effectively block a website within a few hours across the entire network in Iran. Private internet-service providers (ISPs) were forced to either use the bandwidth provided by the government or route their send traffic (which contains the sitevisit requests) through government-issued filtering boxes developed by software companies inside Iran. The boxes work by searching for banned text stringseither keywords or domain namesin the URL requests submitted by users.

In recent years there has been pressure within the Iranian government to show that the filtering of content is based on a legal framework and is not arbitrary. As a result, institutions in charge of internet filtering have evolved. In July 2009, Ahmadinejads government enacted the Computer Crime Law, which had been passed by the parliament a year earlier. According to this law, the Committee in Charge of Determining Unauthorized Websites is legally empowered to identify sites that carry forbidden content and report that information to TCI and other major ISPs for blocking. The committee is headed by the prosecutor general and operates under the supervision of his office. The rest of the panel consists of representatives from 12 governmental ministries and institutes. The law also identifies the violations that might result in a website being marked for filtering. These are IRAN FREEDOM HOUSE Freedom on the Net defined very broadly and cover a variety of topics, ranging from insulting religious figures and government officials to distributing pornographic content and illegal circumvention tools.

Little information is available about the inner workings of the committee. According to the law it should meet biweekly to decide on any website bans, but a TCI vice president recently put the rate of filtering at 200 to 300 websites per day, meaning the bulk of filtering decisions are likely made automatically upon discovery of objectionable content, or by a small technical group in charge. This would leave the committee to decide on only the more controversial blocking decisions, such as the move during the protests to block the website of the Combatant Clergy Association (Majmae Rohanion Mobarez), a pragmaticconservative clerical party linked to Rafsanjani. The official websites of Khatami and a number of Grand Ayatollahs who have criticized the government were also blocked. As the head of two important state bodies, the former president remained an influential member of the establishment, but he had been Ahmadinejads electoral opponent in 2005, and he sometimes appeared to side with the opposition in 2009.

There have been other cases of filtering aimed at websites that operate within the official discourse. A number of websites and blogs belonging to Ahmadinejad supporters who publicly criticized some of his governments policies were also blocked. In such an environment, any website that includes elements of opposition discourse is bound to be targeted. The opposition Green Movement, other political groups, womens rights groups, ethnic and religious minorities, and the Iranian homosexual community fall within the category of opposition discourse and are affected by heavy filtering. In addition to blocking certain content, the Computer Crime Law makes service providers, such as blogging platforms, responsible for any content that appears on their sites. This has led to the suspension of a number of blogs hosted on platforms inside Iran.

The authorities claim that there is a procedure for disputing filtering decisions.

However, the procedure is highly inefficient, even for a prominent conservative blogger, Omid Hosseini-Ahestan, whose site was filtered accidentally. He did not succeed in unblocking his blog through the complaint procedure, but the filter was lifted after highprofile media coverage of the incident.7 The dispute process requires the website owner to disclose his or her personal information and accept responsibility for any misconduct in the future, a commitment that few are willing to make given the risk of severe punishment.

In addition to censorship, the state counters critical content and online organizing efforts by extending state propaganda into the digital sphere. There are at least 400 news websites that are either directly or indirectly supported by the state. They seek to set the agenda by providing partial commentary or publishing rumors. There have also been a large number of government-backed initiatives to promote blogging among supporters of Ahestan blog, On filtering of Ahestan, January 15, 2010.

And during the postelection protests, there were reports of fake user-generated content submitted to Twitter and YouTube by government supporters to mislead the protesters and reporters. Some commentators have argued that propaganda is displacing censorship as the primary means of controlling the internet.Self-censorship is also very extensive, particularly on political matters. The widespread arrests of reporters and activists after the election, as well as perceptions of pervasive surveillance, have created fear among online journalists and bloggers. Many of them either abandoned their online activities or were forced to use pseudonyms. At least 1,500 bloggers who were blogging on political issues with their real identity decided to end their blogs or avoid writing about politics directly in the aftermath of the 2009 election.

Furthermore, the majority of independent content producers lack the financial resources to operate in such a hostile environment. The online advertising market in Iran is exclusively limited to apolitical and pro-government websites. Even businesses based outside Iran avoid political websites to maintain trading relationships with the country. Due to international sanctions against Iran, Google Advertising does not recognize Persian as one of the languages in its advertising system, disadvantaging Persian content producers.

Despite all of these limitations, the internet remains the only means available for Iranian citizens and dissenters to get news and organize themselves. Iranian broadcast outlets are tightly controlled by the authorities, and satellite broadcasting from outside Iran is subjected to heavy jamming. The technical difficulty of engaging in similarly comprehensive censorship of a medium as complex and heavily populated as the Iranian internet may explain the authorities growing reliance on propaganda, misinformation, and physical coercion to counter internet-based activism.

VIOLATIONS OF USER RIGHTS Iranian internet users suffer from routine surveillance, harassment, and the threat of imprisonment for their online activities, particularly those who are more critical of the authorities. The constitution provides for limited freedom of opinion and expression, but numerous, haphazardly enforced laws restrict these rights in practice. The 2000 Press Law, for example, forbids the publication of ideas that are contrary to Islamic principles or detrimental to public rights, none of which are clearly defined. The government and judiciary regularly invoke this and other vaguely worded legislation to criminalize critical opinions.
