The 2019 Internet blackout in Iran was a week-long total shutdown of the Internet in Iran. It was ordered by the Supreme National Security Council and imposed by the Ministry of ICT. The blackout was one of the Iranian government's efforts to suppress the 2019–2020 protests.
During the blackout, Iranian citizens could only access the National Information Network. Mohammad-Javad Jahromi was sanctioned by the United States Department of the Treasury because of his role in Internet censorship in Iran.
The blackout led to an estimated $1 billion to $1.5 billion in damages to the Iranian economy.
