It's been several days that Iran suffers from the massive protests that the increase in gasoline prices roused. Authorities limited access to the Internet all over the country in response.

The network security researcher, Amir Rashidi, from the Center for Human Rights in Iran based in New York, stressed it's the most significant Internet shutdown ever recorded by NetBlocks.

"Internet will return to the life of the Iranian people soon, and the government will continue to develop it," said the minister of telecommunications Mohammad Javad Azari Jahromi.

But since November 16, the Net connection wasn't restored for 75 hours. The government tried to keep some domestic services available for specific users, but in general, citizens were offline.

Previously, during mass protests, authorities used bans or blocked individual web services like Facebook and Twitter to limit communication. This time the scale of the shutdown was utterly complex, and it even took 24 hours to execute the process.

Iran also has been practicing blocking of individual sites; however, the VPN services were still running. And this disconnection showed that political bosses decided to cut off Iranians from the outside world and control information channels that come into the country.
