Iran has imposed internet shutdowns more aggressively in 2026 than at any previous point in its history. What began as a targeted blackout during January’s protest wave has escalated — following the U.S.–Israel war on Iran in late February — into what internet monitoring group NetBlocks has described as the longest and most comprehensive internet shutdown ever recorded in any country.
As of April 2026, most Iranian civilians have spent close to two-thirds of the year in near-total digital darkness. This article explains what happened, when it happened, why the Iranian government does it, what it costs, and what it means for 92 million people cut off from the global internet.
The January 2026 Blackout: What Triggered It
Iran’s 2025–2026 protest wave began in late December 2025, driven by hyperinflation, a collapsing economy under international sanctions, and widespread public frustration with the Islamic Republic’s governance. By early January 2026, protests had spread to multiple cities including Tehran, Isfahan, Shiraz, Kermanshah, and Lordegan.
On 8 January 2026 — the twelfth day of the protests — Iranian authorities imposed a comprehensive internet blackout. According to Chatham House’s International Security Programme, an estimated 92 million citizens were cut off from internet access. The shutdown was not limited to social media platforms or foreign websites — it targeted Iran’s own National Information Network, disconnecting the country internally as well as externally.
The blackout lasted more than 60 hours in its most severe phase, with monitoring group NetBlocks confirming on 11 January that the shutdown had passed the 60-hour mark. Even after partial restoration, severe restrictions remained in place through late January.
What made the January 2026 shutdown different from previous ones was its sophistication. Iranian authorities used military-grade jammers to disrupt civilian Starlink satellite signals — a tool that ordinary Iranians had been using to bypass previous internet restrictions. Within hours of the jammers being activated, 80% of Starlink-dependent traffic was blocked. The government simultaneously issued a “whitelist” that allowed government-affiliated users and state media to continue operating normally — creating a digital divide between authorities and ordinary citizens.
The Iranian Minister of Communications, Sattar Hashemi, acknowledged that the shutdown was costing the economy $35.7 million per day. Online sales fell by 80% during the blackout, and the Tehran Stock Exchange lost 450,000 points over a four-day period.
Trump’s Warning and Iran’s Response
In January 2026, then-U.S. President Donald Trump issued a public warning to Iranian authorities not to use excessive force against protesters. The warning was widely reported inside Iran through the limited connectivity that remained available, and it coincided with the most severe phase of the internet restrictions.
Iranian authorities — consistent with decades of positioning foreign statements as interference — used Trump’s warning as partial justification for tightening control over information flows. The Islamic Republic has consistently framed external pressure as evidence of foreign conspiracy against the state, a narrative that the internet shutdown supported by limiting Iranians’ ability to see and share foreign media coverage of the protests.
Whether Trump’s warning directly accelerated the shutdown is disputed. What is documented is that the timing — and the government’s use of the foreign interference narrative — made it harder for international observers to attribute the crackdown to a single cause.
The February 2026 Wartime Blackout
The January shutdown was severe, but it was followed by something even more dramatic. On 28 February 2026, when the United States and Israel launched joint air strikes on Iranian nuclear and military facilities, internet traffic in Iran dropped dramatically in what Human Rights Watch confirmed was a nationwide wartime blackout.
This second shutdown occurred in the context of active military conflict — the first time Iran had imposed an internet blackout during direct military confrontation with a foreign power. Human Rights Watch issued a statement calling on Iranian authorities to immediately end the shutdown, noting that communications blackouts during conflict place civilians at further risk of harm and contribute to impunity for human rights violations by concealing what is happening on the ground.
The wartime blackout proved far more durable than the January one. By early April 2026, Al Jazeera reported that Iranian civilians had spent close to two-thirds of 2026 in near-total digital darkness, with only a limited and at times slow domestic intranet providing access to state-run news and basic services.
NetBlocks, the internet monitoring organisation, made a striking historical observation: Iran had become the first country ever to have had full internet connectivity and then subsequently lost it by reverting entirely to a national intranet network — effectively disconnecting itself from the global internet.
Iran’s History of Internet Shutdowns
The 2026 blackouts did not emerge from nowhere. Iran has used internet shutdowns as a tool of political control for years, each episode more sophisticated than the last.
In November 2019, the Iranian government imposed a full six-day internet blackout during protests over fuel price increases, shielding the government from international scrutiny as security forces killed hundreds of protesters.
In 2020, protests following the government’s accidental shootdown of Ukraine International Airlines Flight 752 — killing 176 people — were met with internet restrictions.
During the Women, Life, Freedom protests of September to December 2022, authorities imposed a range of internet restrictions including localised and short-term shutdowns.
During the Twelve-Day War between Iran and Israel in June 2025, the Iranian government imposed restrictions. Each episode built on the previous one technically — the 2026 shutdowns represented the culmination of years of investment in digital censorship infrastructure.
What the Shutdown Costs Iran
The economic cost of internet shutdowns is substantial and well-documented. During the January 2026 blackout:
Online sales fell by 80%. Small and medium businesses that depend on digital platforms — e-commerce sellers, freelancers, online service providers — lost income immediately. The Tehran Stock Exchange lost 450,000 points over four days as investors reacted to the instability and information vacuum.
The Iranian Minister of Communications acknowledged a direct cost of $35.7 million per day. Independent analyst Afshin Kolahi estimated in April 2026 that when indirect costs are included — lost productivity, supply chain disruption, financial market impacts — the true daily cost is closer to $70–80 million.
Beyond the economy, the human cost is significant. During blackouts, people cannot access medical information, cannot communicate with family members in other cities, cannot verify safety information during security incidents, and cannot contact emergency services through digital means. Human rights organisations note that blackouts also effectively shield security forces from accountability by preventing documentation of abuses.
How Iranians Cope With Blackouts
Despite the severity of the shutdowns, Iranians have developed remarkable resilience in maintaining communication.
Virtual Private Networks (VPNs) remain widely used when partial connectivity is available, though the government has become increasingly sophisticated at detecting and blocking VPN traffic. During the January 2026 blackout, military-grade jammers specifically targeted Starlink signals — previously one of the most reliable workarounds.
Offline communication networks — word of mouth, in-person coordination, and short-range radio — become critical during blackouts. During the 2026 protests, nightly rooftop chants from residential buildings became a form of protest that required no internet connection — a visible, audible signal of dissent that could not be digitally suppressed.
Diaspora media — Persian-language news organisations and social media accounts run by Iranians outside the country — play a crucial role during blackouts, aggregating information from people with limited connectivity and broadcasting it back into Iran through whatever channels remain available.
The Human Rights Dimension
Human Rights Watch, Amnesty International, and Article 19 have all condemned Iran’s internet shutdowns in 2026 in the strongest terms.
Amnesty International documented that by mid-January 2026, Iranian authorities had arrested thousands of people in connection with the protests. Independent reports indicated that tens of thousands — including children — had been arbitrarily detained. The internet shutdown made it significantly harder to document these abuses, investigate them, or bring international pressure to bear.
Human Rights Watch stated that communications blackouts contribute directly to impunity for human rights violations, place civilians at further risk of serious harm, and violate international human rights law — specifically the rights to freedom of expression, access to information, and peaceful assembly.
The Internet Society and NetBlocks have both argued that internet access has become so fundamental to daily life — for healthcare information, education, financial transactions, and basic communication — that shutting it down constitutes a form of collective punishment against civilian populations.
What This Means for the Future
Iran’s 2026 internet shutdowns represent a new and troubling benchmark in the global use of digital censorship. NetBlocks’ observation that Iran has become the first country to revert from full internet connectivity to a national intranet is historically significant — it represents a deliberate policy choice to sever a nation from the global information ecosystem rather than simply restrict it.
Whether this model proves durable is uncertain. The economic costs are enormous. The political costs — in terms of international isolation and internal resentment — are substantial. And the technical workarounds that citizens develop with every shutdown push the government toward increasingly extreme countermeasures, as the use of military-grade Starlink jammers in January 2026 demonstrated.
For observers in Pakistan and elsewhere in the Muslim world, Iran’s experience is a stark reminder that digital rights and internet freedom are not abstract concerns. They are practical questions about whether ordinary people can access information, communicate with their families, and participate in the modern economy — questions whose answers, as Iran’s 2026 experience shows, can change very rapidly.
