A previous BGP lab focused on the customer side of BGP communities: adding them to BGP updates to influence upstream ISP behavior. Today’s lab focuses on the ISP side of the equation: using BGP communities in a routing policy to implement RFC 1998-style behavior.
Studying for a certification exam is also about grasping real-world concepts. And that’s exactly the approach David Coleman and David Westcott took when writing their CWNA study guide, now in its sixth edition

Ask nearly any Internet user, and they are bound to have their own personal list of favorite sites, applications, and Internet services for news, messaging, video, AI chatbots, music, and more. Sum that question up across a lot of users in a lot of different countries, and you end up with a sense of the most popular websites and services in the world. In a nutshell, that’s what this blog post is about: how humans interacted with the online world in 2023 from what Cloudflare observed.
Building on similar reports we’ve done over the past two years, we have compiled a ranking of the top Internet properties of 2023. In addition to our overall ranking, we chose 9 categories to focus on. One of these is a new addition in 2023: Generative AI. Here are the 9 categories we’ll be digging into:
1. Generative AI
2. Social Media
3. E-commerce
4. Video Streaming
5. News
6. Messaging
7. Metaverse & Gaming
8. Financial Services
9. Cryptocurrency Services
Our method for calculating the results is the same as in 2022: we analyze anonymized DNS query data from our 1.1.1.1 public DNS resolver, used by millions of Continue reading
The 2023 Cloudflare Radar Year in Review is our fourth annual review of Internet trends and patterns observed throughout the year at both a global and country/region level across a variety of metrics. Below, we present a summary of key findings, and then explore them in more detail in subsequent sections.
I always said that the Trivia Pursuit certification tests (or job interviews) are nonsense and that one should focus on fundamentals.
In a recent blog post, Daniel Dib described a fantastic scenario: using a simple “why can’t I connect to a web site” question, explore everything from ARP/ND to DNS and TLS.
Obviously, you’ll never see anything that sane in a certification test. An interactive interview doesn’t scale (beyond CCDE), and using humans (and common sense judgment) creates potential legal liabilities (there were rumors that had been one of the reasons a talk with a proctor who could flunk you was dropped from the CCIE test).

Hi everyone,
First, I’d like to sincerely thank everyone who has supported Highscalability over the years.
We’ve grown together through some interesting times. Massive changes have occurred in how systems are built, and my goal has always been to help people learn how to build them better. I’d like to think that goal was accomplished.
Obviously, for that last several years, things have been quiet around here. This has always been a one programmer show, and for everything, there is a season. The season for me is changing. That means http://highscalability.com is for sale.
My preference is for someone to take HS over and keep it going in some form or another. If you are a content farm, please don’t reply. I’ve never once taken payment for a post and I don’t plan on changing that now.
You get the site, the domain, and the twitter account. If you are not a scam artist and have a reasonable offer, please contact me at [email protected].
Thanks!
Git is one of those tools that lots of people use, but few people truly master. I’m still on my own journey of Git mastery, and still have so very far to go. However, I did take one small step forward recently with the discovery of the ability for Git to automatically rewrite remote URLs. In this post, I’ll show you how to configure Git to automatically transform the URLs of Git remotes.
The key here is the url configuration stanza and the associated insteadOf keyword. Added to your Git configuration—either globally or on a per-repository basis—these configuration options will tell Git to use a different URL every time it encounters the specified original URL.
Here’s an example:
Looking to get started with Ansible for Amazon Web Services? [url "[email protected]:org/"]
insteadOf = "https://github.com/org/"
The [email protected]:org/ is the replacement URL; that is, the URL that you want Git to use. The URL specified by the insteadOf keyword is the original URL; that is, the URL you want Git to replace. As you can see in the example, it’s possible not only to transform HTTPS-based URLs to SSH URLs (or vice versa), but it’s possible to constrain this transformation to repositories belonging to a specific organization or Continue reading
If the original equipment manufacturers of the world had software massive software divisions – like many of them tried to do a two decades ago as they tried to emulate IBM and then changed their minds a decade ago when they sold off their software and services businesses and pared down to pushing tin and iron – then maybe they might have been on the front edge of AI software development and maybe they would have been closer to the front of the line for GPU allocations from Nvidia and AMD. …
