Iran’s 36‑hour internet blackout, triggered by escalating anti‑government protests, represents the most precise and severe digital censorship the country has enacted to date. Experts note that 90 % of international traffic vanished, domestic mobile service collapsed, and even satellite‑based Starlink was jammed in some neighbourhoods. Unlike earlier nationwide blockages, the current shutdown is highly selective: government officials retain access to key platforms such as Telegram, Twitter, and Instagram, while ordinary users are cut off.

This fine‑tuned approach suggests Tehran is developing an internal censorship framework akin to China’s model, potentially allowing the regime to maintain essential communications while suppressing dissent for an extended period. The incident underscores the growing sophistication of state‑controlled internet shutdowns and raises critical concerns for global telecom operators, satellite providers, and digital‑rights advocates. It also highlights the strategic use of whitelisting to balance political control with operational continuity, a tactic that could influence future policy debates on internet governance and the resilience of critical infrastructure in politically volatile regions.
