We also discovered concrete evidence in the leaked data that the regime has attempted to block public DNS servers on a large scale.
According to the extracted configurations and Cloudflare Radar data (see attached image), they deployed strict DNS blocking rules. However, the documents clearly show that they failed to fully block DNS requests to the outside world.
Most of their own servers collapsed during the first tests, forcing them to reroute traffic and rely on DNS forwarding instead. Meanwhile, several ISPs were unable to implement the blocking properly.
We have published the relevant files below. You can scan them yourself and discover the servers and configurations.
