Essential Insights
- Iran’s internet has been fully blackout for over 10 days since February 28, 2026, with traffic plummeting to below 1%, severing roughly 90 million people from global connectivity.
- The shutdown was government-enforced, synchronized across major regions and ISPs, and closely coincided with US and Israeli military strikes.
- The blackout has caused an estimated economic loss of $35.7 million daily and severely impacted online commerce, with online sales dropping by up to 80%.
- Human rights organizations condemn the shutdown as a violation of rights, noting it blocks emergency access and only allows access to pre-approved domestic sites.
The Core Issue
The internet blackout in Iran has lasted over ten days, beginning sharply around 07:00 UTC on February 28, 2026. This outage coincided with U.S. and Israeli military strikes against Iran, which seemingly prompted the government to deliberately sever the country’s online connectivity. Cloudflare Radar data confirms that Iranian internet traffic plummeted by approximately 98%, with HTTP requests falling below 1% of pre-shutdown levels. Independent monitors like NetBlocks verified that this shutdown was state-enforced, not due to cyberattacks or infrastructure failures, indicating a centralized decision rather than isolated failures. The impact has been widespread: Tehran accounts for 65% of traffic, with other key regions completely cut off. The shutdown has hit Iran’s major ISPs—MCCI, IranCell, and TCI—simultaneously, marking it as one of the longest and most severe nationwide shutdowns in recent history. As of now, Iran’s internet remains largely offline, costing the economy millions daily and mounting concerns over human rights violations, especially since the government continues to restrict access to only authorized domestic websites. Overall, this event highlights how geopolitical conflicts can directly manipulate vital digital infrastructure, leaving millions disconnected and vulnerable.
Risk Summary
An extended Internet blackout, like Iran’s, where online traffic drops below 1% of normal levels for over ten days, can severely disrupt any business. When connectivity vanishes, communication stalls, orders go unplaced, and customer service collapses. Consequently, revenue drops sharply, and brand reputation suffers due to lost trust. Moreover, supply chains break down, delaying deliveries and increasing costs. In today’s digital economy, such outages cut off your access to vital data, markets, and remote workforce productivity. Therefore, even a temporary disruption can have lasting financial and competitive impacts, highlighting the critical need for resilient digital infrastructure in business continuity planning.
Possible Actions
In today’s interconnected digital landscape, the swift identification and response to internet disruptions are crucial to minimizing broader societal and economic impacts. When Iran’s internet blackout exceeds ten days, with traffic dropping below 1% of normal levels, prompt remediation becomes essential to restore services, prevent further damage, and safeguard critical infrastructure.
Assessment & Analysis
- Conduct comprehensive network traffic analysis to identify disruption points
- Gather intelligence to determine if outage is malicious or accidental
Containment & Limitation
- Isolate affected network segments to prevent spread
- Disable compromised systems or services swiftly
Restoration & Recovery
- Implement alternative communication channels (e.g., satellite links)
- Deploy backup systems and redundant infrastructure
Remediation & Prevention
- Patch vulnerabilities exploited during the outage
- Enhance network resilience through increased redundancy
- Improve monitoring systems for early detection of anomalies
Communication Strategies
- Inform stakeholders, government agencies, and the public about progress
- Coordinate with ISPs and international bodies for assistance
Policy & Training
- Review and update cybersecurity policies
- Train personnel in incident response and threat mitigation
By adopting these measures, organizations can effectively address the incident’s root causes, restore normal operations efficiently, and bolster defenses against future disruptions.
