Always Check Your Tests Against Faulty Inputs
A while ago, I published a blog post proudly describing the netlab integration test that should check for incorrect OSPF network types in netlab-generated device configurations. Almost immediately, Erik Auerswald pointed out that my test wouldn’t detect that error (it might detect other errors, though) as the OSPF network adjacency is always established even when the adjacent routers have mismatching OSPF network types.
I made one of the oldest testing mistakes: I checked whether my test would work under the correct conditions but not whether it would detect an incorrect condition.
Immich Setup with Docker & External Library (NFS)
Recently, I started self-hosting most of the apps I use, like Memos for note-taking and Paperless-NGX for document management. The next one on the list was Immich. Immich is a self-hosted photo and video backup solution that supports features like facial recognition and automatic uploads.
Memos - Amazing Open Source, Self-hosted Notes App
That being said, I recently stumbled upon another great self-hosted note-taking app called ‘Memos’ I just couldn’t believe that I didn’t know about this until very recently.

Paperless-ngx - Self-Hosted Document Manager
I came across a great self-hosted document manager called ‘Paperless-NGX’. It not only helps with organising documents but also includes OCR functionality

In this post, we’ll look at how to set up Immich as a Docker container and also how to add an NFS share as an external library.
But, Why?
I have a lot of pictures on my NAS that I’ve collected over the years. This includes photos of friends, family, and ones from my older phones. I wanted a way to manage and organise them from one place. I also didn’t want to upload all of them to Google or Apple, which would cost quite a bit. Continue reading

TNO035: Network Engineer and Content Creator – A Career Journey with Kevin Nanns
Kevin Nanns is today’s guest on Total Network Operations. Kevin describes his “Wizard of Oz” moment when he discovered the world of networking. He talks about how he came up through the ranks working a help desk and then in a NOC, and his climb up the certification ladder. We also discuss how AI is...

We have a network automation discussion for you today from sponsor Megaport. At the AutoCon3 conference earlier this year, Luke Gollan presented on a complex network automation project migrating Megaport’s API-driven software defined network from a legacy VXC overlay to an EVPN framework. This helped improve scalability, but was fraught with practical challenges, not the... Read more »Cisco IOS/XE Hates Redistributed Static IPv6 Routes
Writing tests that check the correctness of network device configurations is hard (overview, more details). It’s also an interesting exercise in getting the timing just right:
- Routing protocols are an eventually-consistent distributed system, and things eventually appear in the right place (if you got the configurations right), but you never know when exactly that will happen.
- You can therefore set some reasonable upper bounds on when things should happen, and declare failure if the timeouts are exceeded. Even then, you’ll get false positives (as in: the test is telling you the configurations are incorrect, when it’s just a device having a bad hair day).
And just when you think you nailed it, you encounter a device that blows your assumptions out of the water.
IPB179: IPv6 DNS Gotchas
Let’s talk about common misconceptions regarding DNS and IPv6. We’ve heard these often enough that we felt we should talk through each one. We cover issues including what kind of DNS record types can be returned via IPv6 (and IPv4, too), more details on what really goes on with Happy Eyeballs, and combining A/AAAA records...

What is DNS Delegation and what is it used for? What is new in the Delegation world, and what impact does it have on DNS security and operations? George Michaelson joins Tom Ammon and Russ White for a discussion about DNS DELEG in this episode of the Hedge.
Broadcom Tries To Kill InfiniBand And NVSwitch With One Ethernet Stone
InfiniBand was always supposed to be a mainstream fabric to be used across PCs, servers, storage, and networks, but the effort collapsed and the remains of the InfiniBand effort found a second life at the turn of the millennium as a high performance, low latency interconnect for supercomputers running simulations and models. …

N4N033: OSPF Neighbor Formation and Timers
Our OSPF series continues with a look at OSPF neighbor formation and related timers. We talk about the five major packet types that carry information among OSPF routers, how OSPF routers become neighbors, how they negotiate link-state database exchanges, keep-alive messages, and how they negotiate designated and backup routers when multiple devices are on the...

Cloudflare has servers in 330 cities spread across 125+ countries. All of these servers run Quicksilver, which is a key-value database that contains important configuration information for many of our services, and is queried for all requests that hit the Cloudflare network.
Because it is used while handling requests, Quicksilver is designed to be very fast; it currently responds to 90% of requests in less than 1 ms and 99.9% of requests in less than 7 ms. Most requests are only for a few keys, but some are for hundreds or even more keys.
Quicksilver currently contains over five billion key-value pairs with a combined size of 1.6 TB, and it serves over three billion keys per second, worldwide. Keeping Quicksilver fast provides some unique challenges, given that our dataset is always growing, and new use cases are added regularly.
Quicksilver used to store all key-values on all servers everywhere, but there is obviously a limit to how much disk space can be used on every single server. For instance, the more disk space used by Quicksilver, the less disk space is left for content caching. Also, with each added server that contains a particular Continue reading
The World’s Most Powerful Server Embiggens A Bit With Power11
If you need a big, badass box that can support tens of terabytes of memory, dozens of PCI-Express peripheral slots, thousands of directly attached storage devices, all feeding into hundreds of cores that can span that memory footprint with lots of bandwidth, you do not have a lot of options. …

Many developers, data scientists, and researchers do much of their work in Python notebooks: they’ve been the de facto standard for data science and sharing for well over a decade. Notebooks are popular because they make it easy to code, explore data, prototype ideas, and share results. We use them heavily at Cloudflare, and we’re seeing more and more developers use notebooks to work with data – from analyzing trends in HTTP traffic, querying Workers Analytics Engine through to querying their own Iceberg tables stored in R2.
Traditional notebooks are incredibly powerful — but they were not built with collaboration, reproducibility, or deployment as data apps in mind. As usage grows across teams and workflows, these limitations face the reality of work at scale.
marimo reimagines the notebook experience with these challenges in mind. It’s an open-source reactive Python notebook that’s built to be reproducible, easy to track in Git, executable as a standalone script, and deployable. We have partnered with the marimo team to bring this streamlined, production-friendly experience to Cloudflare developers. Spend less time wrestling with tools and more time exploring your data.
Today, we’re excited to announce three things:
Demystifying Ultra Ethernet
The Ultra Ethernet Consortium (UEC), of which Arista is a founding member, is a standards organisation established to enhance Ethernet for the demanding requirements of Artificial Intelligence (AI) and High-Performance Computing (HPC). Over 100 member companies and 1000 participants have collaborated to evolve Ethernet, leading to the recent publication of its 1.0 specification, which will drive hardware implementations that significantly boost cluster performance.
The Art Of The GPU Deal
Perhaps the most interesting conversation that has happened so far in the White House in 2025, at least from the point of view of the IT sector, is when Nvidia co-founder and chief executive officer, Jensen Huang, put on his Sunday best suit and visited President Donald Trump to presumably talk about technology, AI, trade, and war on July 10. …
