David Belson

AVFTCN 043 – David Belson interview, and creating a community around emerging technlogy Greetings from the Vancouver airport! I'm about to board a ridiculously long (14.5 hours! 🤯) flight to Brisbane, Australia, and then on to another 6-ish hour flight to Bali, Indonesia, for ICANN 87. If you will…

New audio: I recently had a chance to sit down with @dbelson.com and talk about #Internet disruptions, measuring the Internet, agentic AI, cheeseburgers and more.. we've known each other for years, but it was fun to learn more of his background and interests - soundcloud.com/danyork/tdyr...

It's always great to talk with @danyork.bsky.social, and this time it was as a guest on his podcast. We talked about the future of Internet measurement, the challenges of measuring Internet disruptions, and the potential impact of agentic AI. (And cheeseburgers...) soundcloud.com/danyork/tdyr...

Impact to local #Internet connectivity clearly visible in Watch The Net and @ioda.live measurements: watchthenet.com/e/country/PA ioda.inetintel.cc.gatech.edu/country/PA

An island-wide power outage in #Cuba has impacted #Internet connectivity across the country. Starting around 17:45 UTC, @radar.cloudflare.com data shows traffic dropping by >50% compared to the prior week, and @ioda.live shows a 10% drop in successful active probing.

New exhibit has dropped in the Internet History Initiative reading room, thanks to some excellent new indexing of 19th century Boston newspapers (h/t: Boston Public Library via Harvard Library's @institutional.org ) internethistoryinitiative.org/blog/2026/09/04/before-the-internet/

For 10 years, the #KeepItOn campaign has united civil society to push back against internet shutdowns and defend human rights. Today, the movement is stronger than ever. Celebrate with us and join the #KeepItOn movement: www.accessnow.org/keepiton-10-...

The #earthquake in #Colombia had a nominal impact on #Internet connectivity, per @radar.cloudflare.com data. Traffic dropped 35% compared to the prior week. Traffic at an ASN level appeared to recover quickly. Some loss of announced IP space, suggesting infrastructure damage as well.

Paging @emophilips.bsky.social

Data from @radar.cloudflare.com shows a [complete loss of announced IPv4 & v6 space](radar.cloudflare.com/routing/lc?d... ) from Flow St. Lucia starting at 21:00 UTC, and with it, a complete loss of traffic from the network, impacting connectivity island-wide. stlucianewsnow.net/flow-reports...

I wonder if the second book in the series was called “Foreman Farley Causes an Internet Outage”

A widespread power outage in #Jamaica is impacting #Internet traffic from the island. @CloudflareRadar shows traffic fell ~0200 UTC, with the largest impact to FLOW Jamaica. The provider acknowledged the issue in a Facebook post. radar.cloudflare.com/traffic/jm?d... www.facebook.com/FlowJamaica/...

In a Facebook post, Syria's Ministry of Communications & Information Technology announced that there will be no communication cuts during the general exams this year, in contrast to #Internet shutdowns implemented in past years. www.facebook.com/SyMOCAIT/pos... www.google.com/search?q=syr...

Cable damage has taken Digicel Haiti completely offline, as @radar.cloudflare.com shows that #Internet traffic and announced IP space all fell to zero just after 22:00 UTC (18:00 local). Similar problems occurred multiple times in 2025. radar.cloudflare.com/traffic/as27... x.com/jpbrun30/sta...

Just to keep today's partial restoration of Iranian internet connectivity in perspective, please take a look at this overall timeline. Iran has a long way to go to get back to pre-Jan-8 levels of traffic volumes. #DigitalBlackOutIran‌

Traffic data from @radar.cloudflare.com shows a rapid increase in traffic from #Iran starting ~11:00 UTC (14:30 local). Traffic from providers including #Irancell, #MCCI, and #TCI is up significantly. radar.cloudflare.com/traffic/ir?d...

I was one of the 1100 impacted by yesterday's layoff at Cloudflare. Thankful that I had the opportunity to work on @radar.cloudflare.com over the past 4+ years, evolving it into a trusted industry resource. Would love to continue working with #Internet data in my next role...

DNSSEC failure broke the .de TLD, risking millions of German domains. See how 1.1.1.1 used "serve stale" and Negative Trust Anchors to restore resolution during the incident. Read the full technical breakdown. https://cfl.re/4we2Nsz

May 5 .de DNSSEC issues as seen through 1.1.1.1 Resolver data on Radar: - Increased DS record request traffic share, from <1% to >10% - Increased SERVFAIL response share, from <2% to 50% - ~4x increase in query volume - >80% drop in certificate issuance radar.cloudflare.com/tlds/de?date...

Gov’ts continue to shut down the internet during school exams, claiming it prevents cheating. There’s no evidence it works. But there’s clear evidence it violates rights + cuts people off from essential services. Here’s what’s on our watch list for 2026 🔽 www.accessnow.org/campaign/no-...

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
