NetBlocks said on March 26 that the blackout had entered its 27th day, with national connectivity hovering around 1% of normal levels. A Human Rights Watch analysis said Cloudflare Radar recorded a 98% drop in internet traffic on Feb. 28, the day the latest phase of the war began.
That timeline matters. As Reuters reported, the current conflict began with U.S. and Israeli strikes on Iran on Feb. 28 and has since widened across the Middle East. In that environment, cutting connectivity does more than suppress dissent; it strips civilians of one of the few tools they have to track danger in real time.
Why the Iran internet blackout is more than a communications outage
Inside Tehran, the blackout is changing how people process risk. Associated Press reporting from the capital found that residents were relying on friends, anxious gatherings and pieced-together phone updates to learn where bombs had landed, while one resident estimated that only a sliver of the public still had limited VPN access.
The information squeeze is also becoming part of the wider crackdown. Reuters reported on March 24 that Iranian police had arrested 466 people over alleged online activity deemed harmful to national security, including accusations of filming sensitive sites, sharing anti-government material and cooperating with hostile actors. When access is restricted and the risks of posting rise, the supply of independent evidence shrinks even further.
The result is a vacuum that serves both censorship and confusion. In wartime, that can distort casualty reporting, delay outside verification and leave families abroad dependent on fragments of unverifiable information. For a country already under pressure from sanctions, repression and airstrikes, the blackout is compounding isolation rather than containing panic.
The Iran internet blackout follows a familiar pattern
This is not the first time Tehran has reached for a shutdown during a national crisis. During the 2019 fuel-price protests, NetBlocks documented a near-total national blackout after progressive disconnections spread across the country. In 2022, during the Mahsa Amini protest movement, Reuters described Iran as a global hotspot for internet blackouts as authorities again restricted access during a nationwide crackdown.
The current crisis also did not begin with the latest wave of airstrikes. Reuters reported in January 2026 that Tehran had already kept much of the country cut off from the global web after anti-government protests, hammering businesses and leaving uncertainty over when full access would return. The war appears to have hardened and prolonged that blackout, not created it from scratch.
That continuity is what makes the present moment especially dangerous. Iran is not dealing with a one-off outage caused by damaged infrastructure or temporary overload. It is facing a recurring model of digital control, now layered on top of an active war. The longer that model holds, the harder it becomes to verify events on the ground, assess civilian risk in real time and build trust in any official account of the conflict.
Until connectivity is restored, the Iran internet blackout will remain more than a technology story. It is a war story, a human-rights story and, for millions of Iranians, a daily reminder that fear grows fastest when facts cannot move.
