August Rule 11 Academy Update

I’ve been working on new material over at Rule 11 Academy. This month’s posts are:

  • BGP Route Reflector Lab
  • The Clos Fabric (history)
  • The Default Free Zone
  • Network Addresses
  • BGP Policy Entrance Selection (2)
  • Interview Rubric Sample
  • BGP Policy Entrance Select (1)
  • Interviewing Background

    • This brings us up to a total of 39 lessons. Each lesson should be about 15 minutes, so about 10 hours of material so far. The trial membership will take you through the end of the year. After the first of the year, the trial membership will last 2 months.

Hedge 238: What Went Wrong? (Crowdstrike)

The massive failure resulting from a failed update to 8.5 million Windows hosts by Crowdstrike will live in Internet history for years to come. The failure will be studied by engineering teams and college classes to understand what went wrong and how we can stop this from happening in the future. Derick Winkworth (@cloudtoad), Eyvonne Sharp, Tom Ammon, and Russ White hang out at the hedge to talk about what happened and lessons learned from a network engineering perspective.

The Hedge 237: What’s Wrong with Vendors?

Looking at changes in the market in the last ten years, it certainly seems like vendors work less toward innovation and more towards locking customers in to revenue streams.

Recent events involving CrowdStrike’s Falcon security software have underscored a critical lesson across the industry: the importance of having a robust, secure release process.


My analysis of the event has a lot of similarities with my reflections on the Optus outage last year, the incident underscores the critical issue of resilience in IT infrastructure, particularly in systems that lack diversity.


But recovery is just the beginning. What’s sure to follow is a barrage of regulatory oversight, hard feelings among the IT community, and a tough reminder that even a small slip-up in a software update can have catastrophic global consequences.


Over the years, there has been a lot of discussion on if VLAN 1 in Cisco switches is special or not. Does it have any characteristics that other VLANs donﾒt?


Are you considering the switch from network engineer to cloud engineer? This post wo’t teach you everything needed to become a cloud expert, but hopefully, it will create a level of comfort and familiarity such that you can start your journey to the cloud from here.


The creation of voluntary standards is an idea that may seem easier than imposing regulations. But devising voluntary standards presents unique challenges, different from Continue reading

On the other hand, these same minimal overheads imply that DNS over UDP cannot perform prompt detection of packet loss and cannot efficiently defend itself against various approaches to tampering with the DNS, such as source address spoofing, payload alteration and third-party packet injection. Perhaps most importantly, the way UDP handles large payloads is a problem.


User interface (UI) design is currently experiencing a transition from traditional graphical user interfaces (GUIs) to systems designed to recognize a personﾒs gestures and movements.


The U.S. Federal Trade Commission (FTC), along with two other international consumer protection networks, announced on Thursday the results of a study into the use of “dark patterns” — or manipulative design techniques — that can put users’ privacy at risk or push them to buy products or services or take other actions they otherwise wouldn’t have.


One of the most concerning aspects of social media is that much of its influence evades our notice. We don’t realize that we’re being influenced, or shaped to think a certain way, or view the world through a specific lens.

The Hedge 235: Copyrights and Centralization

Join us as Tom, Eyvonne, and Russ hang out for another roundtable. We start the show talking about Tom’s plant (is it real or … ??). What does copyright have to do with Internet Service Providers? Should the two topics be related at all? What can the IETF do about Internet centralization?

Thanks for listening—and please reach out if you have a topic you’d like to hear about, or a guest you’d like to hear.
