when smaller becomes easier

"The Iranian regime has developed, with the assistance of European telecommunications companies, one of the world's most sophisticated mechanisms for controlling and censoring the Internet, allowing it to examine the content of individual online communications on a massive scale.

China's vaunted "Great Firewall," which is widely considered the most advanced and extensive Internet censoring in the world, is believed also to involve deep packet inspection. But China appears to be developing this capability in a more decentralized manner, at the level of its Internet service providers rather than through a single hub, according to experts.

The difference, at least in part, has to do with scale: China has about 300 million Internet users, the most of any country. Iran, which has an estimated 23 million users, can track all online communication through a single location called the Telecommunication Infrastructure Co., part of the government's telecom monopoly. All of the country's international links run through the company."
