Iran’s Internet Blackout and the National Information Network

概览

This episode of Marketplace Tech examines what the transcript calls the longest internet blackout in Iran’s history, taking place as U.S. and Israeli airstrikes against Iran continue into their fifth week.

The central point is that Iran is not experiencing a total loss of connectivity. Amir Rashidi of the Mian Group explains that people can still access the National Information Network, or NIN, a domestic network controlled by the regime, while global internet services, independent news, and social media are cut off.

The discussion moves from the mechanics of Iran’s domestic network to the human consequences: blocked access to war information, disrupted emergency and police functions, and limited workarounds that cannot realistically serve a country of 90 million people.

分段落总结

[00:01] Iran’s internet blackout during wartime

[事实] The episode opens by describing the situation as the longest internet blackout in Iran’s history. [事实] The host says U.S. and Israeli airstrikes against Iran are continuing into their fifth week. [事实] International monitors say Iran’s regime has cut off internet access since the war began. [事实] Amir Rashidi says the blackout is not total because Iranians still have access to the National Information Network, or NIN, which is fully controlled by the regime.

[00:58] Internet shutdowns are not new in Iran

[事实] Rashidi says shutdowns, disruptions, and censorship have existed in Iran since the internet became available there. [事实] He says internet shutdowns often happen when people protest, sometimes at neighborhood level, city level, or nationwide. [推测] The current wartime shutdown is presented as an escalation of an established state practice rather than a wholly new tactic.

[01:22] What works and what is blocked on the NIN

[事实] Rashidi says people can still use domestic services, such as an Iranian equivalent of Uber Eats, to order coffee online. [事实] He says access to Google, social media, and international news sites such as BBC and CNN is unavailable. [事实] He describes access to those outside services as “absolutely zero.”

[01:49] Domestic services also carry censorship

[事实] Rashidi explains that the NIN has physical infrastructure and application-layer services built on top of it. [事实] He says Iran has domestic equivalents for many international services, including national email and a national search engine. [事实] He says searching the word “war” on the national search engine returns no results. [推测] The example suggests that censorship is not limited to blocking foreign platforms but is also embedded inside domestic services.

[02:30] War alerts and the limits of domestic connectivity

[事实] The host compares the issue with Ukraine, where people have used apps to report bomb strikes and send alerts. [事实] Rashidi says this kind of reporting is not technically possible on the NIN because the Iranian government is highly sensitive about information related to bombing, explosions, and war. [事实] He says the internet freedom community outside Iran has developed an app called Mahsa Alert. [事实] He says Mahsa Alert still requires access to the internet, which brings the issue back to the shutdown itself.

[03:21] Safety consequences for civilians and emergency services

[事实] Rashidi says he has heard from people who wanted to go to the doctor but could not get access. [事实] He describes a family member reporting a suspicious car and calling the Iranian equivalent of 911. [事实] He says police told the caller they could not check the plate number because they did not have internet access. [推测] The blackout affects not only speech and news access but also basic public safety and emergency response.

[04:16] Workarounds exist but do not scale

[事实] The host asks about workarounds such as VPNs, satellite internet, and Starlink. [事实] Rashidi says tools and technologies exist and can help people communicate locally when they cannot reach the outside world. [事实] He says Iran has a population of about 90 million people. [事实] He says supporting a country of that size would require far more resources.

[05:00] Government rationale and Rashidi’s interpretation

[事实] Rashidi says the state would describe the shutdown as a measure to protect people. [事实] He says he believes the real goal during the war is absolute control over narratives about the war. [事实] He connects this to protest shutdowns, saying the government also tries to control communication and prevent people from mobilizing against it. [推测] The episode frames the shutdown as both an information-control strategy and a tool for limiting civic organization.

[05:51] Credits and production

[事实] The episode identifies Amir Rashidi as being from the Mian Group. [事实] Asus Alvarado and Nicolas Guillaume produced the episode. [事实] Megan McCarty Carino hosts Marketplace Tech.

[06:04] Post-roll promotion for How We Survive

[事实] The transcript ends with an APM promotion for How We Survive, hosted by Amy Scott. [事实] The promoted podcast is described as covering climate solutions. [事实] The promo mentions geoengineering ideas including balloons in the stratosphere and space-based sunshades.

播客点评/总结

[推测] This episode’s value is its concise explanation of how a country can appear connected domestically while being cut off from the global internet. The distinction between the NIN and the open internet is the clearest technical and political takeaway.

[事实] The strongest moments are the concrete examples: domestic food delivery still working, a national search engine returning no results for “war,” Mahsa Alert being limited by the shutdown, and police being unable to check a license plate.

[推测] The main limitation is that the transcript relies on one expert interview and does not include direct comments from Iranian officials, affected civilians beyond Rashidi’s examples, or detailed measurement data from the monitors mentioned at the start.

[推测] The episode is best suited for listeners interested in digital rights, wartime information control, internet infrastructure, and the real-world consequences of censorship beyond social media access.
