NetBlocks and Kentik: Iran further restricted what little internet connectivity remained to curb VPNs, possibly to forestall protests during Festival of Fire
Iran's internet, which has been heavily throttled by the regime since the outbreak of war, has gone even darker over the past 48 hours …
Context & Ripple Effects
This is an escalation of the blackout reported earlier this month, when users were turning to Starlink, decentralized messaging apps, and VPNs as connectivity fell to roughly 1% of normal levels. The new restrictions target those remaining paths rather than merely reducing general access.
It also extends a recurring pattern: connectivity fell across multiple providers during January protests, following earlier restrictions on major social platforms during unrest.
First-order effects
- Iranian users face reduced access to VPN-based communications and services at a moment when the remaining domestic connection was already heavily throttled.
- VPN providers and other circumvention tools become less reliable for reaching users inside Iran; NetBlocks and Kentik’s measurements provide outside evidence of the further restriction.
Second-order effects
- People seeking to communicate or obtain information are pushed further toward alternative channels already cited in coverage, including satellite access and decentralized messaging tools.
- A move from broad throttling to limiting VPN access raises the operational burden for circumvention providers, which must adapt to a more hostile and less predictable network environment.
Third-order effects
- If repeated, this pattern points to internet shutdowns becoming a layered control strategy: reduce baseline connectivity, then target the tools that restore access.
- The contest between network controls and circumvention technologies may increasingly determine whether digital communication remains resilient during periods of unrest, though the available coverage does not establish which tools will prove durable.
The trend: Iran’s restrictions illustrate a broader shift from blocking individual platforms toward suppressing the connectivity and circumvention layers that enable independent communication.
