65% of client HTTPS request traffic is post-quantum encypted. But what does server-side PQ support look like? A new Radar graph tracks PQ support across customer origins, and a new tool enables users to test any Web server for PQ support. Learn more at radar.cloudflare.com/post-quantum

We're now publishing Key Transparency audit data for E2EE messaging apps on Cloudflare Radar, showcasing the Key Transparency logs that Cloudflare audits, providing a window into the health and activity of these critical systems. Learn more at radar.cloudflare.com/key-transpar...

#ASPA is an emerging standard intended to help further improve routing security. You can now track ASPA deployment at a global, country/region, and ASN level on Cloudflare Radar, including real-time searching for ASPA entries. Explore it at radar.cloudflare.com/routing#rpki... #RPKI

Cloudflare Radar has added new tools for monitoring PQ adoption, KT logs for messaging, and ASPA routing records to track the Internet's migration toward more secure encryption and routing standards. https://cfl.re/4tY6GB0

Nice interview w/ @dbelson.com about what the internet is all about in 2026, and how complicated it has grown: from growth, to geo-political realities, to wondering whether you're dealing with humans or not. nexttechtoday.com/people/qa-wi...

#SuperBowlLX featured many creative ads, and as we have done in the past, we used aggregated, anonymized 1.1.1.1 DNS Resolver traffic to identify some of the most popular ones. Traffic growth was calculated by comparing request volume to a pre-game average baseline. 🧵below:

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.

On November 18 Cloudflare experienced a service outage. Here's a detailed breakdown of what happened. https://cfl.re/43Bw8AI

Getting very close to the end of my author client @bzotto.bsky.social’s ”Go Computer Now!” book Kickstarter project! It’s a great read, and wild to learn about a significant entry in the history of personal computing that was almost entirely forgotten. Colorful characters and a tale well told!

Last few days for funding “Go Computer Now!”, a book about the nearly forgotten, pioneering Utah computer firm Sphere (1975–1977) that you likely *never heard about*. (I edited the book.) Help us get over the last hump at www.kickstarter.com/projects/bzo... @bzotto.bsky.social

Cloudflare used historical data to investigate reports of potential new firewall tests in Turkmenistan. Shifts in TCP resets/timeouts across ASNs corroborate large-scale network control system changes. https://cfl.re/4nwaCV3

IPv4 scarcity drives widespread use of CGNAT, a practice in ISPs that places many users behind one IP address, along with their collected Internet activity. We introduce the method we’ve developed to detect large-scale IP sharing globally and mitigate the issues that result.

Backed!

Proud of the @radar.cloudflare.com team for the work done to add three great new data sets to Radar -- we're constantly expanding visibility into what's happening on the #Internet! 🧵

Hopefully it won’t suck.

I didn't realize my Macbook Air had a dialup modem... 🤣

Multiple reports of a brief #Starlink outage earlier this morning corroborated by a significant drop in HTTP requests between 04:00-05:00 UTC. Large burst of #BGP announcements seen at that time as well. Announced IP address space also saw some shifts. radar.cloudflare.com/routing/as14...

For Apple devices, it's already started to grow over the last several months as beta and RC versions of iOS and MacOS 26 became available.

Keep an eye on radar.cloudflare.com/adoption-and... next week as Apple releases their latest OS upgrades - we expect to see Post-Quantum adoption grow!

Who here do I know that hosts their own webpages or blogs? A postdoc colleague and I would like to ask a few fast questions about your traffic patterns over the last 5 years. (please reshare for reach thank you!)
