Internet connectivity in Iran has almost completely disappeared on Wednesday, according to website monitoring firms, as war with Israel enters its sixth day.
Netblocks, a company that tracks online access around the world, wrote on x This Iran is “now in the middle of a near-total national internet cessation.”
The company’s assessment has been confirmed by other online monitoring organizations.
Data collected by IodaWhich is a system that “monitors the Internet infrastructure connectivity in near-real-time, with the aim of identifying macroscopic Internet interruptions,” showed Wednesday the sudden collapse of Internet connectivity in Iran.

David Belson, the head of data understanding of an online infrastructure company Cloudflare, told Techcrunch that online traffic levels in Iran “are now ~ 97% below, where they were at the same time a week ago,” and showed the company’s own data is Iran Internet connectivity.
News on the Internet interruptions come because Iran and Israel are currently involved in military conflict. Iran has also experienced several cyber attacks since the beginning of the latter conflict, including the hacks of Important Iranian bank And Crypto exchange. Following the attacks, Iranian newsroom Irib said that Israel launched a “massive cyber war” against Iran, and Iranian officials reportedly began to restrict access to the country’s internet.
However, it is unclear what is responsible for the collapse of Iran’s Internet, said Belson.
“In similar cases of near-complete internet interruptions, we often see a simultaneous drop in an announced IP address space, meaning that the networks of the country are no longer visible on the Internet. However, we have not seen such action in this case,” Belson told Techcrunch.
“We can only see that the traffic has fallen – the data does not tell us why it fell,” added Belson.
Other online monitoring experts, such as Doug Madory, who works for Kentik, also saw the same collapse.
“Many Iranian service providers now offline in a second national internet suspension in so many days,” Madory wrote on x. “This interruption is more severe than yesterday.”
