Alp Toker

Alp Toker is the director of NetBlocks, a civil society organisation that monitors internet freedom and tracks real-time network disruptions worldwide. NetBlocks uses a global network of probes and IODA-style measurement infrastructure to detect and document internet shutdowns, traffic throttling, and platform blocks imposed by governments. It has become the primary real-time data source for journalists, human rights organisations, and policymakers tracking state-directed internet disruptions.

In the May 2026 Iran conflict, Toker and NetBlocks were the primary technical source for documenting Iran's tiered internet rollout — tracking the Supreme National Security Council's operationalisation of a "white internet" system that maintained connectivity for regime-approved institutions while degrading general public access. NetBlocks data was cited by Article 19, DFRLab, and major international news organisations covering The Information-control aspect of the conflict.

Toker's work combines network measurement with public communication: NetBlocks provides real-time alerts on X (formerly Twitter) and issues formal reports used in UN human rights submissions and national court proceedings. His organisation has documented shutdowns in Iran, Russia, Belarus, Myanmar, and Sudan, among others.
