Iran's internet connectivity has held at 1% of normal capacity for five consecutive days — the most severe communications shutdown in the country's recorded history, according to NetBlocks and Georgia Tech's IODA. When the blackout crossed 48 hours on 1 March, its economic cost was already estimated at $35.7 million per day . It has now run more than twice that long.
Whether the shutdown is government-imposed, strike-induced, or both remains unclear. US forces have struck communications infrastructure among their more than 1,000 targets . The Iranian government has also imposed shutdowns during every major domestic crisis in recent years. During the November 2019 fuel price protests, authorities severed connectivity for roughly a week — a blackout that concealed what Reuters later documented as approximately 1,500 deaths at the hands of security forces. The Amnesty International documentation of snipers targeting heads and torsos during Iran's January 2026 crackdown was itself only possible because connectivity had been partially restored afterward. At 1% capacity, no comparable documentation can occur.
The consequences run in multiple directions. For Iran's 88 million residents, the blackout means inability to locate family members, coordinate evacuations, or access emergency information while strikes continue across 24 provinces. For International humanitarian law, the damage may prove permanent: investigations depend on contemporaneous evidence — photographs, communications records, medical documentation, witness testimony gathered close to events. Every day the blackout continues, that evidentiary foundation erodes, regardless of which parties' conduct a future investigation would examine.
The shutdown also produces an asymmetric information environment. The striking parties — the United States and Israel — retain full situational awareness through military intelligence, surveillance, and reconnaissance systems. The Iranian government maintains internal military and government communications networks. The civilian population caught between them has access to neither.
