An Iranian woman walks past a mobile phone shop at the Valiasr Square in Tehran on April 19, 2026. The internet blackout, which was imposed soon after the US and Israel attacked Iran on February 28, was already the longest nationwide shutdown on record as of April 5, according to NetBlocks, which says it has now lasted more than 50 days. Iran's extremely restricted local intranet has been working throughout the war, allowing people to connect to domestic websites, but it's still insufficient for normal businesses to work in a country whose economy has already crippled by international sanctions.
