The first quarter of 2026 saw a surge in Internet disruptions, from nationwide shutdowns in Uganda and Iran to unprecedented drone strikes on cloud infrastructure. We explore the data behind these events using Cloudflare Radar. https://cfl.re/4cJz8yJ

From War to Sovereignty: The Normalization of Tiered Internet in Iran

On February 28, the #Internet was shut down in #Iran for the second time in 2026. Two months later, it remains largely unavailable. However, increased allowlisting of external sites, and availability of "Internet Pro" access has driven nominal increases in traffic visible in the back half of April.

The IODA team and Project Ainita have documented a measurement-based perspective of the ongoing shutdown cutting Iran off from the global Internet. The Iranian regime has morphed a "stealth Internet blackout" from June 2025 into a new Internet. ioda.inetintel.cc.gatech.edu/reports/from...

Interesting observation: Sunday-Thursday each week, between 0900-2000 UTC, Googlebot appears to ramp up its crawling of plain text files. A similar pattern is visible for JavaScript files as well, Monday-Thursday, between 1600-1200 UTC. radar.cloudflare.com/bots/directo...

We love seeing @radar.cloudflare.com data cited in research papers and other publications. In support of that, shareable widgets on Radar now contain a "generate citation" icon in the action bar, featuring BibTeX, APA, MLA, Chicago, and RIS styles.

A recent target of airstrikes, Sharif University of Technology (AS12660) went offline at 23:12 UTC (2:42am local) today. apnews.com/video/ict-bu... @ioda.live view: ioda.inetintel.cc.gatech.edu/asn/12660-IR...

It is a teeny increase, but in recent weeks Cloudflare Radar now shows #ipv6 crossing the 40% proportion threshold in traffic. It has been hovering at 39% for awhile. We'll just have to wait and see if that is the new floor. https://radar.cloudflare.com/adoption-and-usage#ipv4-vs-ipv6

We've also extended bot traffic visibility on Radar to support sub-national filters. Radar now shows bot traffic trends and which networks generate the most bot traffic from your state/region. Examples: radar.cloudflare.com/bots/2267056 radar.cloudflare.com/bots/5549030

Cloudflare Radar is a rich source of BGP and routing insights and data. To recognize its importance, we've broken out "Routing" into its own section, featuring Overview, RPKI, and Anomalies pages, with more to come very soon. Explore for yourself at radar.cloudflare.com/routing

Iran is currently enduring its longest-ever internet shutdown, which began shortly after the Feb-28 airstrikes. My latest post covers all of 2026, outages within the whitelisted traffic, and other observations from our data. #DigitalBlackOutIran‌ www.kentik.com/blog/interne...

🌍 Small i18n improvement: If you are using Radar in a language other than English, we now display translated geolocations (geonames alternate names) where available. For example, see radar.cloudflare.com/pt-pt/traffi... or radar.cloudflare.com/ja-jp/traffi...

Speed test results are now shared between speed.cloudflare.com and radar.cloudflare.com/speedtest. Detailed results are shown on Speed, while summary and country/network comparisons are shown on Radar, and users can now easily switch between the two views.

The latest #Internet shutdown in #Iran has now entered its 7th day. Traffic remains well under 1% of previous levels. The distribution of remaining traffic by ASN has shifted significantly since the shutdown was implemented. radar.cloudflare.com/traffic/ir radar.cloudflare.com/explorer?dat...

My latest for the @cloudflare.social blog, looking at Q4 2025 Internet outages and disruptions as seen through @radar.cloudflare.com data and graphs.

Today’s reminder that I am old.

The IODA team completed a comparative analysis of the ongoing Internet shutdown in Iran to shutdowns during Bloody November in 2019, Women Life Freedom Movement in 2022, and the Israel-Iran War in 2025. Please read and reach out with any questions. ioda.inetintel.cc.gatech.edu/reports/a-co...

In this post for @kentik.bsky.social, I analyze the ongoing internet shutdown in Iran — one of the most severe communications blackouts in history. #DigitalBlackoutIran #IranRevoIution2026 www.kentik.com/blog/from-st...

Beginning to see signs of life for the internet of Iran! #DigitalBlackoutIran #IranianRevolution2026 An increase in traffic flowing into Iran began at 00:12 UTC (3:42am local) — note this restoration is still only currently at 0.2% of the bits/sec we were seeing prior to the shutdown on Jan-8.

Some #Internet connectivity may be returning in #Iran, with traffic levels spiking ~50x just after midnight UTC on Saturday, January 17 (03:30 local time). Follow radar.cloudflare.com/traffic/ir?d... for the latest traffic stats. #DigitalBlackoutIran

NEW: The internet in Iran is nearly completely shut down, according to internet monitoring firms. The blackout comes in the midst of countrywide protests that have lasted for days after spikes in prices and shortages of basic goods. The govenrment has responded with a violent crackdown.

Internet monitoring firms and experts say Iran’s internet has almost completely shut down, as protests spread through major cities.
