The The monitoring organization NetBlocks said At around 20:00 local time on Thursday, its live data showed “Tehran and other parts of Iran are entering a digital blackout as internet connectivity drops from multiple providers; new incidents are likely to follow regional blackouts, and coverage of events is likely to be severely limited as protests spread.”
A source in the capital told CBS News that “there were huge crowds all over Tehran. Unprecedented.”
They also said the internet was down for most people in the city, but some with stronger and more reliable business accounts could still get online.
The blackout came as Iranians started shouting against the regime from their windows, after exiled Iranian Prince Reza Pahlavi, son of the US-backed former shah, called for his voice to be heard.

Many young and tech-savvy advertisers have become adept at dealing with the restrictions, but it’s a cumbersome process, and when the regime slows down internet speeds during politically sensitive times, the entire system can become unusable.
