好的，我现在需要帮用户总结一篇关于伊朗互联网中断的文章，控制在100字以内。首先，我得仔细阅读文章内容，抓住关键信息。 文章提到，美国和以色列对伊朗发动了袭击，导致伊朗全国互联网几乎完全中断。根据NetBlocks的数据，全国连接率下降到正常水平的4%左右。Cloudflare也确认了这一点，互联网流量几乎为零。这种情况与去年伊朗和以色列的冲突期间相似，可能表明政府有意限制网络连接。 此外，文章还提到主要新闻网站如IRNA和ISNA出现严重故障，人们转向社交媒体获取信息。这些细节都很重要，但需要在100字内简洁表达。 接下来，我要组织语言，确保涵盖主要事件：袭击导致的网络中断、连接率下降、与去年冲突的相似性、政府可能的干预以及人们使用社交媒体的情况。 最后，检查字数是否符合要求，并确保语句通顺、准确。 </think> 美国和以色列对伊朗发动军事打击后,伊朗全国互联网几乎完全中断,全国连接率降至正常水平的4%左右,主要新闻网站瘫痪,人们转而通过社交媒体获取信息。 2026-2-28 10:37:7 Author: securityaffairs.com(查看原文) 阅读量:6 收藏
Iran ’s Internet near-totally blacked out amid US, Israeli strikes

Iran experienced a near-total internet blackout as Israel and the U.S. launched strikes, according to NetBlocks.
Internet access across Iran was drastically reduced on Saturday as Israel and the United States carried out strikes against the country, according to independent and non-partisan global internet monitor NetBlocks.
Network data indicated a near-total nationwide blackout. The national connectivity is down to about 4% of normal levels, amid ongoing military strikes by Israel and the United States.
“Confirmed: Network data show #Iran is now in the midst of a near-total internet blackout with national connectivity at 4% or ordinary levels. The incident comes amid US and Israeli combat operations and matches measures used during last year’s war with Israel.” wrote NetBlocks.

NetBlocks noted that the disruption resembles measures previously seen during last year’s conflict with Israel, suggesting authorities may have intentionally restricted connectivity amid escalating tensions.
Cloudflare also confirmed that Internet traffic in the country has dropped to effectively zero as of 18:45 UTC (22:15 PM local time), signaling a complete shutdown in the country and disconnection from the global Internet.
Iran’s internet shutdowns are widely viewed as tools for regime control. Teheran may use it to curb information flows, and reduce foreign pressure or cyber threats against critical infrastructure. By cutting or throttling connectivity during crises, authorities hinder external cyber operations and limit reconnaissance while also disrupting internal coordination, protest organization, and real-time reporting of damage or abuses.
Large-scale cyberattacks reportedly struck Iran alongside Saturday’s military strikes by Israel and the U.S., disrupting major domestic platforms. According to local media, websites of key news agencies, including IRNA and ISNA, experienced significant outages. As state media faltered, many Iranians turned to foreign opposition sites and social media platforms such as Instagram and Telegram for updates, wherever internet access remained available.
