像纳姆达尔·巴格哈伊-亚兹迪这样的海外伊朗人自一月大规模抗议以来，与伊朗国内亲属的联系都非常有限，这段时间在导弹击中其德黑兰街道后，他一度连续几天不知道亲人是否还活着。自那以后，德黑兰已经两次切断互联网连接，第二次在美国与以色列打击后于2月28日开始，被称为伊朗历史上最长、最严厉的一次，并且可能会长期持续。

近二十年来，伊朗通常在国内异议和境外导弹袭击后，通常通过关闭BGP路由进行断网，例如2019年起义和2022年部分时期，这会阻断进出伊朗的一切流量。当前则是不同路径：政府建立了“国家信息网络”（NIN）这种封闭型国内系统，效仿中国、朝鲜和俄罗斯，在维持国内网络运转的同时阻断Facebook、WhatsApp等境外平台，并让自动化系统在获批应用中扫描反政权言论。

由于国际路由仍保持开启，国家可对获批个人和机构按需开放全球网络访问并剥夺多数人的权限；肯提克网络情报公司的道格·马多里称，这对绝大多数人来说等同于“长期甚至无限期”中断。Psiphon在一月关闭前（且网络仅局部恢复时）记录到超过1840万伊朗用户，精英白名单流量在三月十五日也低于1%并出现下降，而跨出国境的Starlink终端（几万台）仍使大量画面外流，但这些方法技术复杂、极高风险（持有终端可能被判死刑），使得在9300万伊朗人中只有几百千人能实际实现绕过。

People living abroad like Namdar Baghaei-Yazdi have had very limited contact with families in Iran since the January protests, a period marked by days of uncertainty after a missile strike on his Tehran street left him unsure whether his relatives were still alive. Since then, Iran has cut internet connectivity twice, with the second shutdown starting February 28 after U.S. and Israeli strikes and described as the longest and harshest in Iranian history, potentially permanent.

For nearly two decades, Iran had typically disconnected internet traffic by disabling BGP routes during unrest, as in 2019 and partly in 2022, when all in-and-out traffic was blocked. This time is different: authorities built the National Information Network, a closed domestic system modeled on China, North Korea, and Russia, preserving domestic function while blocking foreign media and apps like Facebook and WhatsApp and monitoring approved platforms for anti-regime content.

With global routes still up, the state can selectively grant or deny global access, so Doug Madory of Kentik says this can amount to an indefinite shutdown for most users. Psiphon counted over 18.4 million Iranian users in January before the shutdown during partial restoration, elite whitelist traffic under 1% also dropped by March 15, and only a few hundred thousand people out of 93 million are realistically able to bypass through technically complex and dangerous methods such as Starlink terminals.
