Digital Twins are a Living and Breathing Network Diagram
Visibility into network intent is a growing problem for NetOps teams. Learn how digital twins create a living and breathing network diagram with network change preparation, troubleshooting, and compliance benefits that result in more confidence and increased implementation speed.Internet disruptions overview for Q4 2022
Cloudflare operates in more than 250 cities in over 100 countries, where we interconnect with over 10,000 network providers in order to provide a broad range of services to millions of customers. The breadth of both our network and our customer base provides us with a unique perspective on Internet resilience, enabling us to observe the impact of Internet disruptions.
While Internet disruptions are never convenient, online interest in the 2022 World Cup in mid-November and the growth in online holiday shopping in many areas during November and December meant that connectivity issues could be particularly disruptive. Having said that, the fourth quarter appeared to be a bit quieter from an Internet disruptions perspective, although Iran and Ukraine continued to be hotspots, as we discuss below.
Government directed
Multi-hour Internet shutdowns are frequently used by authoritarian governments in response to widespread protests as a means of limiting communications among protestors, as well preventing protestors from sharing information and video with the outside world. During the fourth quarter Cuba and Sudan again implemented such shutdowns, while Iran continued the series of “Internet curfews” across mobile networks it started in mid-September, in addition to implementing several other regional Internet shutdowns.

Video: 2023 Network Engineer Path to Success
David Bombal kindly invited me to have another chat talking about the future of networking in late 2022. The resulting (masterfully edited) video is already on YouTube. Hope you’ll enjoy it as much as I enjoyed chatting with David.
Hedge 162: Geoff Huston and Going Dark
Encrypt everything! Now! We don’t often do well with absolutes like this in the engineering world–we tend to focus on “get it down,” and not to think very much about the side effects or unintended consequences. What are the unintended consequences of encrypting all traffic all the time? Geoff Huston joins Tom Ammon and Russ White to discuss the problems with going dark.

Leveraging the power and versatility of Cloudflare's Ruleset Engine, Waiting Room now offers customers more fine-tuned control over their waiting room traffic. Queue only the traffic you want to with Waiting Room Bypass Rules, now available to all Enterprise customers with an Advanced Purchase of Waiting Room.
Customers depend on Waiting Room for always-on protection from unexpected and overwhelming traffic surges that would otherwise bring their site down. Waiting Room places excess users in a fully customizable virtual waiting room, admitting new visitors dynamically as spots become available on a customer’s site. Instead of throwing error pages or delivering poorly-performing site pages, Waiting Room empowers customers to take control of their end-user experience during unmanageable traffic surges.
Additionally, customers use Waiting Room Event Scheduling to manage user flow and ensure reliable site performance before, during, and after online events such as product restocks, seasonal sales, and ticket sales. With Event Scheduling, customers schedule changes to their waiting rooms' settings and custom queuing page ahead of time, with options to pre-queue early arrivers and offload event traffic from their origins after the event has concluded.

Relationships between Layer-2 (VLAN) and Layer-3 (Subnet) Segments
Sometimes it takes me years to answer interesting questions, like the one I got in a tweet in 2021:
Do you have a good article describing the one-to-one relation of layer-2 and layer-3 networks? Why should every VLAN contain one single L3 segment?
There is no mandatory relationship between multi-access layer-2 networks and layer-3 segments, and secondary IP addresses (and subnets) were available in Cisco IOS in early 1990s. The rules-of-thumb1 claiming there should be a 1:1 relationship usually derive from the oft-forgotten underlying requirements. Let’s start with those.

Day Two Cloud 178: Implementing Zero Standing Privilege (Sponsored)
On today's sponsored Day Two Cloud podcast we talk about zero standing privilege with strongDM. Zero standing privilege goes beyond just-in-time credentials to a model where no credentials pre-exist, but are created in real-time and paired with appropriate permissions built from policy, also created in real-time. Can such a thing be accomplished technically---and without irritating all your end users? StrongDM's Sebastian Mankowski is here to make the case.
