The gradual trend of IT organizations spending more on dedicated or shared cloud infrastructure than they do on non-cloudy gear continues its inevitable, glacial transformation. …
As 2021 Wound Down, Big Clouds Did Record Spending On Infrastructure was written by Timothy Prickett Morgan at The Next Platform.
2022 only has 19 days of existence but so far this January, there have already been four significant Internet disruptions:
1. An Internet outage in The Gambia because of a cable problem.
2. An Internet shutdown in Kazakhstan because of unrest.
3. A mobile Internet shutdown in Burkina Faso because of a coup plot.
4. An Internet outage in Tonga because of a volcanic eruption.
The latest Internet outage, in the South Pacific country of Tonga (with 169 islands), is still ongoing. It started with the large eruption of Hunga Tonga–Hunga Haʻapai, an uninhabited volcanic island of the Tongan archipelago on Friday, January 14, 2022. The next day, Cloudflare Radar shows that the Internet outage started at around 03:00 UTC (16:00 local time) — Saturday, January 15, 2022 — and is ongoing for more than four days. Tonga’s 105,000 residents are almost entirely unreachable, according to the BBC.
When we focus on the number of requests by ASN, the country’s main ISPs Digicel and Kalianet started to lose traffic after 03:00 UTC and by 05:30 UTC January 15, 2022, Cloudflare saw close to no traffic at all from them, as shown in the graph below.

Remember the BGP anycast lab I described in December 2021? In that blog post I briefly mentioned a problem of extraneous IBGP sessions and promised to address it at a later date. Let’s see how we can fix that with a netlab plugin.
We always knew that it’s impossible to implement every nerd knob someone would like to have when building their labs, and extending the tool with Python plugins seemed like the only sane way to go. We added custom plugins to netlab in late 2021, but I didn’t want to write about them because we had to optimize the internal data structures first.

Stream 1 October 2013: CCIE#1346 didn’t like it. In fact, he despised it so much that even after the edits he never posted the recommendation on his LinkedIn profile. The endorsement passage was strong and to the point; after having had his book, Developing IP Multicast Networks, for years and using it constantly, I […]

I’m excited to announce that I recently joined Cloudflare in Japan as Vice-President and Managing Director, to help build and expand our customer, partner base, and presence in Japan. Cloudflare expanded its network in Japan in 2010, just months after launching. Now, 12 years later, Cloudflare is continuing its mission to help build a better Internet in Japan and across the globe, and I’m looking forward to being able to contribute to that mission!
In my 35-year career in the IT industry, I have been fortunate enough to work with some of the biggest technology companies in the world, working in various roles in both sales and technical sides of the business. I consider this one of my biggest strengths. In addition, working in the IT industry has allowed me to acquire industry knowledge across a number of different solutions such as custom development, packaged systems (ERP, CRM), MS Office products, and cloud solutions.
Most recently, I was director of the Enterprise Business Group for Japan at AWS, where I was responsible for all commercial industries such as Manufacturing, Process, Distribution, Retail, Telecommunications, Utility, Media, Service, Pharmaceuticals, among others. Continue reading
Most of the large companies and institutions we cover here at The Next Platform have already been in the AI/ML trenches, particularly the hyperscale web and media companies (where much of this work began) and in high performance computing. …

Vast Data Eyes A Role In The Datacenter Beyond Storage was written by Jeffrey Burt at The Next Platform.
Monitoring is a critical part of any computer system that has been brought in to a production-ready state. No IT system exists in true isolation, and even the simplest systems interact in interesting ways with the systems “surrounding” them. Since compute time, memory, and long-term storage are all finite, it’s necessary at the very least to understand how these things are being allocated.
Perhaps this question seems contrived. However, it’s always worth spending a moment thinking about reasons before adding any technical complexity to a distributed system! After all, they are already quite complicated! So why does the Calico eBPF data plane support metrics through Prometheus and Grafana?
Well, the Calico eBPF data plane is production ready and widely deployed, so a well-configured Kubernetes cluster with the Calico eBPF data plane correctly enabled will be stable and reliable. However, distributed systems are inherently complex and when dealing with them, it is generally good practice to instrument and baseline metrics wherever they are available. Doing so provides many benefits, especially for capacity planning, change management, and as an early-warning or smoke-testing system.
Additionally, seeing a running distributed system fully instrumented can be Continue reading
The Full Stack Journey is back for 2022, and kicking off the year Scott shares recommendations for learning new technologies based on his own career experiences and the technology transitions he's lived through, including virtualization to networking and networking to containers. Scott also shares four key takeaways for learners in the tech industry.

This article was originally posted on the Packet Pushers Ignition site on June 15, 2021. There’s a growing need at the provider edge to let customers provision services closer to users and data sources. What do I mean by the ‘provider edge’? In the case of application infrastructure with low-latency connectivity for mobile, industrial, and […]

One of ipSpace.net subscribers asked for my opinion about Adaptive IP, a concept promoted by one of the optical connectivity vendors. As he put it:
My interest in Carrier Ethernet moving up to Layer 3 is to see if it would be something to account for in the future.
A quick search resulted in a marketecture using Segment Routing (of course) and an SDN controller (what else could one be using today) using Path Computation Element Protocol (PCEP) to program the network devices… and then I hit a regwall. They wanted to collect my personal details to grace me with their whitepaper, and I couldn’t find even a link to the product documentation.
