Egress network quality of service on Red Hat OpenShift (opens on the source site)
Red Hat ·
In this article, we explore what network quality of service (QoS) means, preview an upcoming native capability that's addressing it declaratively, and then step through a practical solution you can deploy today using the Linux traffic control (tc) command. We'll set up a full reproducer lab, run it, and look at real test results that demonstrate production traffic maintaining throughput while background traffic is deprioritised under contention. The post Egress network quality of service on Red Hat OpenShift appeared first on Red Hat Developer.
2026 Birthday week: network performance update (opens on the source site)
Cloudflare now ranks as the fastest provider across 74% of the top 1,000 global networks. By incorporating background telemetry from Cloudflare Challenge Pages, we have expanded our real-user measurement scale while maintaining user privacy.
How recurring network maintenance exposed 6 bugs (opens on the source site)
Jane Street does a lot of network maintenance over the weekends. In each maintenance, a cabinet may lose connectivity for 15 to 25 minutes. Our internal Kafka infrastructure is supposed to be resilient to these partitions, and reconnect when connectivity resumes. For several months this year, it didn’t: processes segfaulted, leaked hundreds of thousands of sockets, or crashed in a surge of half a million TCP connections.

Debugging my new network, when 10 Gigabit Ethernet Runs at 300 Megabits (opens on the source site)
I've been moving my home storage over to a UniFi UNAS Pro 8 as part of a larger homelab moderization. My main IRONHEART (the ultimate PC from a few years back) desktop now has an Intel E610-XT2 10GbE card, the NAS is on 10GbE, and there's a Minisforum MS-01 miniPC on the same network with a 10GbE SFP+ connection running Immich and Portainer and a few other things. Everything says 10 gigabit. Windows says 10 gigabit. UniFi says 10 gigabit. SMB copies are using the correct NIC but my file copies are running at around 100 to 200 megabits per second which is sad making. Naturally, I blamed the…
Workshop Basel day three (opens on the source site)
See also: day one, day two. There is only one thing that is better than two days of HTTP workshop, and that is of course three days of HTTP workshop. The final day of this edition of the series started out with us again shuffling around where we parked ourselves around the big table. Except … Continue reading Workshop Basel day three →
Workshop Basel day two (opens on the source site)
If you missed it. I already described day one. Caffeinated and ready, we all gathered in the same spacious room as yesterday, but seated in new places as “suggested” by our captain. Some of us even remembered to move over the name tags we wrote yesterday to our new seats. No time was wasted on … Continue reading Workshop Basel day two →
Workshop Basel day one (opens on the source site)
On this hot summer’s day in Basel, Switzerland, the seventh HTTP workshop started. These events tend to work roughly the same way and the people in the room are also to large extent familiar and known since previous editions. Forty people in a meeting room, where we take turns in doing short talks on HTTP … Continue reading Workshop Basel day one →

How I Chose the Best Managed Network Switch for My Home Lab (opens on the source site)
Update (one year later): The verdict is in. I went with the TP-Link SG2210XMP-M2, and after a full year in the rack it's been running flawlessly: fanless, multigig, VLANs and not a single issue.Continue reading...
Network Rack for Small Office (Build Guide) (opens on the source site)
Last week I walked into an empty 5 × 4 ft storage room. By the end of the week, that blank space held a fully functional network core designed to keep a small professional office online through power cuts, ISP hiccups, and future growth.Continue reading...
Practicing Playwright: API Testing, Intercepting Network Requests, and Mocking APIs (opens on the source site)
How would you intercept a network request and use the data for assertions? Mock a network request using those assertions? And make sure that all data is loaded in the UI before making your assertions, and that all tests can pass when run? We will be walking through Butch Mayhew's code that answers all of these questions, part of his LinkedIn Learning course: Playwright Essential Training. We will be examining the shopping cart test site PracticeSoftwareTesting.com and looking at code on Butch's companion GitHub site on how to mock out the API and use them in the UI tests. Playwright has a lot…

Slack ·
The Problem: Legacy Tooling and Its Limitations Currently, Slack utilizes a hybrid approach to network measurement, incorporating both internal (such as traffic between AWS Availability Zones) and external (monitoring traffic from the public internet into Slack’s infrastructure) solutions. These tools comprise a combination of commercial SaaS offerings and custom-built network testing solutions developed by our…
Can you reverse engineer our neural network? (opens on the source site)
A lot of “capture-the-flag” style ML puzzles give you a black box neural net, and your job is to figure out what it does. When we were thinking of creating our own ML puzzle early last year, we wanted to do something a little different. We thought it’d be neat to give users a complete specification of the neural net, weights and all. They would then be forced to use the tools of mechanistic interpretability to reverse engineer the network—which is a situation we sometimes find ourselves facing in our own research, when trying to interpret features of complex models.
Feedzai TrustScore: Enabling Network Intelligence to Fight Financial Crime (opens on the source site)
Feedzai ·
By Sofia Guerreiro, Ricardo Ribeiro Pereira, Iker Perez, Jacopo BonoDetecting financial fraud is like finding a moving needle in a shifting haystack. Fraud accounts for a tiny fraction of financial transactions, often less than 0.1%. At the same time, fraudsters are constantly adapting their tactics to evade detection. And this happens within a live and dynamic environment, where financial behaviors and technologies are changing over time. In short, this is an exceptionally difficult problem for financial institutions.With the rise of digital banking and new technologies like GenAI, this…
Network booted, home initialized (opens on the source site)
I had a lot of fun writing blog posts in the past about my home lab and some of my personal infrastructure so I thought I would do the same as we built out our office. Much like moving into a new place, the first thing I always plan to have setup on move-in day is internet. We did the same with our office as well. Before we even had any real furniture, we made sure that we had a network connection. You may recognize that furniture from the garage. For the office I really wanted our network infrastructure to be off-the-charts good. Everyone knows shitty internet is a productivity killer. Since…
Monitor Network Traffic with EtherApe (opens on the source site)
I wanted to count packets coming back and forth while telnet'ing to test out some different email protocols on our mail server and found this nifty little utility: it's called EtherApe. Supposedly it's a clone of Etherman, which, if it has clones, probably costs money. (http://picasaweb.google.com/lh/photo/jNWdHI8V5W1IIMh1W1NKYw?feat=embedwebsite">sudo apt-get install etherape There will be a few libraries that are dependencies, but I forget which they are.
