Iran has entered its tenth consecutive day of near‑total internet blackout, with traffic levels still below 1% of normal activity. According to Cloudflare Radar and NetBlocks, the shutdown is deliberate, government‑enforced, and one of the most severe connectivity disruptions ever recorded globally.
What Happened
- Start of blackout: Began on February 28, 2026, at 07:00 UTC, coinciding with joint US and Israeli military strikes.
- Immediate collapse: HTTP traffic dropped by 98% almost instantly, across all major regions.
- Nationwide impact: Tehran (65% of traffic), Fars, Isfahan, Razavi Khorasan, and Alborz all flatlined to near zero.
- ISP shutdown: The three largest providers — MCCI, IranCell, and TCI — went dark simultaneously, pointing to coordinated action at the national infrastructure layer.
Scale of the Blackout
- Duration: Surpassed 240 hours (10 days) by March 10, making it the second longest in Iran’s history, after January 2026 protests.
- Population affected: Roughly 90 million Iranians cut off from the global internet.
- Economic toll: Estimated losses of $35.7 million per day, with online sales plunging by up to 80%.
- Human rights impact: Human Rights Watch condemned the blackout as a violation of fundamental rights, warning it blocks access to emergency information and escalates civilian risks.
What Remains Online
Only pre‑approved websites on Iran’s National Information Network (NIN) remain accessible. This domestic intranet allows limited government‑sanctioned services but isolates citizens from global communication, commerce, and information.
Why It Matters
- Digital isolation: Internet shutdowns sever citizens from the global economy and information ecosystem.
- Political control: Connectivity is being used as a lever of state power, silencing dissent and limiting external visibility.
- Global precedent: Iran’s blackout underscores how governments can weaponize infrastructure to control populations.
Final Thought
Iran’s prolonged blackout is more than a technical disruption — it is a humanitarian crisis in the digital age. Cutting off 90 million people from the internet for weeks at a time demonstrates how connectivity has become a frontline in geopolitical conflict. For defenders of digital rights, the lesson is clear: resilience against shutdowns — through decentralized networks, satellite connectivity, and mesh systems — is now as critical as cybersecurity itself.
