Since I work a lot with clustered VMs , I’ve ended up spending a lot of time trying to figure out how DNS lookups work. I applied ‘fixes’ to my problems from StackOverflow without really understanding why they work (or don’t work) for some time.
QUIC version 1 is officially formalized, and QUIC deployments will now move away from using temporary draft versions to the newly minted version 1.
The state of the network after one week of operation.
At RIPE 81, a group of enthusiastic researchers and practitioners from industry and academia discussed with the RIPE community what role RIRs and LIRs could take on in the SCION next-generation Internet architecture. More than 80 BoF participants discussed this question, wanting to learn more about…
HAProxy 2.4 adds features such as support for HTTP/2 WebSockets, authorization and routing of MQTT and FIX protocol messages, DNS resolution over TCP, and more.
There have been several allegations of this since the handover of the Freenode infrastructure to its new custodians, but I can now provide a first-hand account of one incident — because I am the victim of it.
I needed a very basic 'Internet sharing' router setup with one of my Raspberry Pis, and I thought I'd document the setup process here in case I need to do it again. I should note that for more complex use cases, or where you really need to worry about security and performance, you should use something like OpenWRT…
A warm welcome to a new IRC network!
Matrix, the open protocol for secure decentralised communications
One of the best ways to find ways to improve performance, we’ve found, is to work closely with our customers. We love shared troubleshooting sessions with their own engineering teams to find and eliminate bottlenecks.
One of my favorite books is 2013 "High Performance Browser Networking" by Ilya Grigorik. Besides a wealth of actionable advice, the book is illustrated with captivating real life stories.
No corporate parables or historical insights this week, just the odd and sometimes amusing tale of the author's multi-decade quest for internet connectivity.
There are requirements that make software engineers sweat. Massive distribution to thousands of nodes. High reliability and availability. Multiple distinct platforms. Rapid network growth. This is the world SpaceX’s Starlink program, which has set a goal to provide high-speed broadband internet to locations where…
>25% of the Tor network’s exit capacity has been attacking Tor users
I love Europe, and I want to see the European Union succeed. I also love the Internet, and I want to see it thrive as well. And it therefore pains me that it now appears that the European Union might inadvertently be picking an ugly fight with “The Internet”. UPDATE: I am EXCEPTIONALLY happy to report that through…
Matrix, the open protocol for secure decentralised communications
This post is part of a series about the wonderful world of clusters. Check out the first post for an overview of what clusters are all about. In this post we will take a peek under the hood of our hosting infrastructure and walk through how we made hosting work in a multi-cluster world. Hosting overview If you didn't…
For years, Wi-Fi packet capturing in the Mac has always worked reliably out of the box. Unfortunately, packet capturing is now broken in the new M1 Mac.
In Linux 5.13 ethtool gains an interface for querying IEEE and IETF statistics. This removes the need to parse vendor specific strings in...
Cellebrite makes software to automate physically extracting and indexing data from mobile devices. They exist within the grey – where enterprise branding joins together with the larcenous to be called “digital intelligence.” Their customer list has included authoritarian regimes in Belarus, Russi...
BGP is the glue between all of the thousands of border routers that make up the internet (you can find this post (battleships) and this post (EvE) as a crash course on how BGP works).
It’s time for the Internet to move on to more secure software, and that’s why our Memory Safety Initiative is coordinating work to make further improvements to the Rustls TLS library.
Everyone knows that on most systems you can specify IPv4 addresses just 4 decimal numbers separated with periods (dots). Example: 192.168.0.1 Useful when you for example want to ping your local wifi router and similar. "ping 192.168.0.1" Other bases The IPv4 string is usually parsed by the inet_addr() function or at…
This article is part of a series on (European) innovation and capabilities. In a break from the usual GPS/Galileo, DNA and C++ posts, here is a bit on 5G and national security. It turns out that through PowerDNS and its parent company Open-Xchange, we know a lot about how large scale European communication service…
Support for QUIC and HTTP/3 is now enabled by default in Firefox Nightly and Firefox Beta. HTTP/3 will be available by the end of May.
