It's time for another annual roundup from the world of IP addresses. Let’s see what has changed in the past 12 months in addressing the Internet and look at how IP address allocation information can inform us of the changing nature of the network itself.
I had a wierd experience which made me realize that the internet is probably dead.
Dotted around London, there are a number of private hotels that aren’t the sort of hotel you might expect – they’re needed to make mobile phones work on the London Underground.
Thanks HN folks for all the comments. To clarify a bit, the cables are pulled through PVC conduits under the flooring before being buried in cement. Currently the hypothesis for why the cable disintegrated so quickly is hydrolysis. Singapore is extremely humid after all. A second possibility is that I keep the…
For the past several months, I’ve been receiving and then ignoring a steady stream of concerning emails from Sendgrid, the popular email delivery service owned by Twilio that I use for sendin…
To kick off 2026, I had clear objectives in mind: decommissioning my trusty VPS and setting up its successor. Embracing a complete paradigm shift, I built myself a container-centric, declarative, and low-maintenance setup for the years to come.
On December 28th, I delivered a speech entitled " A post-American, enshittification-resistant internet " for 39C3, the 39th Chaos Communications Congress in Hamburg, Germany. This is the transcript of that speech.
A proof of concept demonstrating how to use the Hinge dating app as a C2.
Setting up WireGuard VPN on FreeBSD 14.3: PF firewall, routing between networks, and peer-to-peer VPN between FreeBSD and Arch Linux
A small HTTP-header tribute to Sir Terry Pratchett
Crystal radios are famous for doing something almost magical: picking up broadcast signals with nothing more than a diode, an antenna, and a pair of headphones. They’re the simplest RF receivers yo…
subsea cables, internet infrastructure, telecom infrastructure, 2Africa, new subsea cable projects, layer 1 pricing on key international routes,
Let’s relearn web caching together.
If you were 5 microseconds late today, blame it on NIST. Their facility in Boulder Colorado just had its power cut for multiple days. After a backup generator failed, their main ensemble clock lost track of UTC, or Universal Time Coordinated. But even if you used the NTP timing servers they run, they were never off by…
For two days in September, Afghanistan had no internet. No satellite failed; no cable was cut. This was a deliberate outage, mandated by the Taliban government. It followed a more localized shutdown two weeks prior, reportedly instituted “to prevent immoral activities.” No additional explanation was given. The timing…
Firstyear's blog
lol. I minted a new TLS cert and it seems that OpenAI is scraping CT logs for what I assume are things to scrape from, based on the near instant response from ...
Rant ahead: I hate TLS “Inspection” software with a burning passion and I wish we collectively as an industry would just knock it the fuck off and stop pretending it’s some great security benefit. Every time I encounter it, in whatever form, it’s a gigantic headache that makes everyone’s life worse off and as far as I…
Before we go any further, one thing that I want to make clear is that the word assume is going to be doing some heavy lifting throughout this post. This was a rabbit hole that I recently went down …
I wrote a browser extension to try and make finding random, independent websites more fun.
ACME, a brief history of one of the protocols which has changed the Internet Security Changelog 03 December 2025: article announced on Mastodon, LinkedIn and X. 03 December 2025: J.C. Jones published his reflections about 10 years of Let’s Encrypt. A must read! 03 December 2025: J.C. has also been kind enough to…
Experiences with the Matrix protocol, Matrix Synapse server, bridges, and Element mobile apps.
In Ukraine suicide drones strike critical infrastructure regularly. Some outages are caused directly by the attacks - destroyed power plants, substations, transformers, power lines, some are scheduled in advance - power grid wasn’t designed to work while some of its power plants and transformers are destroyed and are…
Imgur started blocking UK users. Rather than installing a VPN on every device, I set up a network-wide proxy that tunnels Imgur traffic through a VPN automatically.
Let's explore and deobfuscate the input stack on Linux. Our aim is to understand its components and what each does. Input handling can be divided into two parts, separated by a common layer. We’ll try to make sense of all this, one thing at a time, with a logical and coherent approach.
[BROKEN LINK: blog/google-cloud-s-outage-should-not-have-happened-and-they-seem-to-be-missing-the-point-on-how-to-avoid-it-in-the-future.pre-processed.org], another global IT outage happened (dèjá vu strikes again in our industry). This time at cloudflare(Prince 2025). Again, taking down large swaths of the internet…
How much do you remember from elementary school? I remember vinyl tile floors, the playground, the teacher sentencing me to standing in the hallway. I had a teacher who was a chess fanatic; he painted a huge chess board in the paved schoolyard and got someone to fabricate big wooden chess pieces. It was enough of an…
