Kristijan Taskovski asked an interesting question related to my BGP AS-prepending lab:
I’ve never personally done this on the net but….wouldn’t the BGP origin code also work with moving one’s ingress traffic similarly to AS PATH?
TL&DR: Sort of, but not exactly. Also, just because you can climb up ropes using shoelaces instead of jumars doesn’t mean you should.
Let’s deal with the moving traffic bit first.

What happens when you let a bunch of people work on different aspects of a solution without them ever talking to each other? You get DNS over IPv6. As nicely explained by Geoff Huston, this is just one of the bad things that could happen:

Around 30 years after we got the first website, the powers that be realized it might make sense to put this is how you access a web server information (including its IPv4 and IPv6 address, and HTTP(S) support information) directly into DNS, using HTTPS Resource Records. It took us long enough 🤷♂️

Today on Heavy Networking, sponsored by Juniper, we’ll talk about how Juniper’s Apstra software can help you operate your on-prem data center more like a public cloud; meaning service provisioning that’s repeatable, standardized, and straightforward to consume. We’ll also talk about how Apstra now works with Terraform to help streamline network self-service.

Two years ago, Cloudflare undertook a significant upgrade to our compute server hardware as we deployed our cutting-edge 11th Generation server fleet, based on AMD EPYC Milan x86 processors. It's nearly time for another refresh to our x86 infrastructure, with deployment planned for 2024. This involves upgrading not only the processor itself, but many of the server's components. It must be able to accommodate the GPUs that drive inference on Workers AI, and leverage the latest advances in memory, storage, and security. Every aspect of the server is rigorously evaluated — including the server form factor itself.
One crucial variable always in consideration is temperature. The latest generations of x86 processors have yielded significant leaps forward in performance, with the tradeoff of higher power draw and heat output. In this post we will explore this trend, and how it informed our decision to adopt a new physical footprint for our next-generation fleet of servers.
In preparation for the upcoming refresh, we conducted an extensive survey of the x86 CPU landscape. AMD recently introduced its latest offerings: Genoa, Bergamo, and Genoa-X, featuring the power of their innovative Zen 4 architecture. At the same time, Intel unveiled Sapphire Rapids as Continue reading
Terry Slattery joins Tom and Russ to continue the conversation on network automation—and why networks are not as automated as they should be. This is part one of a two-part series; the first part of this conversation was posted as episode 203.
When I announced the lifetime ipSpace.net subscription in early September, I also mentioned that you won’t be able to purchase any ipSpace.net subscription after December 31st, 2023.
As of today, you have 30 days left to decide, and don’t wait till the last minute – I plan to turn off the purchasing process sometime during the business hours of December 31st as I hope to have more interesting things to do in the evening.
As Kubernetes becomes more mainstream and overall “stable,” organizations need a way to get both enterprise support and proper upgrade paths. Brendan Burns, co-founder of Kubernetes, joins the show to discuss Kubernetes LTS—long-term support.
