As we suspected, the Iranian government has begun rolling out internet whitelisting in a gradual, step-by-step manner. We believe this document will help you uncover the truth behind the operation and identify those responsible.

It reveals exactly how the staged whitelisting allows censors to systematically discover and neutralize the remaining bypass techniques—detailing how they detect them and why they have chosen this precise method. It also contains several other valuable insights worth noting.

Unfortunately ongoing infrastructure changes and continuous mass reloading of firewalls (which you see as 2 to 4 hour connection to outside on these days ) on every ISP are clear signs that a class-based national internet is now being implemented at the country-wide level.

Although this may look like a security upgrade, it is more like moving into a house with a bomb already planted inside. The proof is the massive infrastructure shutdown they adopted from the US.
