TL;DR
Network metrics from monitoring group NetBlocks show Iran has been under a near-total internet blackout for 24 hours, with national connectivity falling to roughly 1% of normal levels. The outage began with loss of service on backbone provider TCI in Kermanshah and has spread to Tehran and other regions as protests enter their 12th day.
What happened
Independent network measurements reported by NetBlocks indicate that Iran's internet has been largely cut off for 24 hours. The disruption began with confirmed loss of connectivity on the national backbone operator TCI in Kermanshah as demonstrations spread, and subsequently expanded to include Tehran and multiple other areas. Live metrics show national connectivity has flatlined at about 1% of ordinary levels, following a sequence of regional shutdowns. NetBlocks characterizes the situation as a nationwide blackout imposed amid escalating protests and rising casualties, and notes the move will severely constrain reporting and private communications. The group says the digital censorship measures aim to suppress protest activity and conceal reports of regime violence. NetBlocks' updates marked a 12-hour flatline at one point before confirming the outage continued to 24 hours.
Why it matters
- A near-total blackout limits the ability of residents and journalists to share real-time information from the ground.
- Connectivity falling to ~1% of normal levels effectively severs most online communications nationwide.
- NetBlocks says the measures impede fundamental rights and can obscure reports of violence linked to protests.
Key facts
