Etienne-Victor Depasquale, a researcher at University of Malta, is trying to figure out what technologies service providers use to build real-life metro-area networks, and what services they offer on top of that infrastructure.
If you happen to be involved with a metro area network, he’d love to hear from you – please fill in this survey – and he promised that he’ll share the results of the survey with the participants.

We have blocked Kiwifarms. Visitors to any of the Kiwifarms sites that use any of Cloudflare's services will see a Cloudflare block page and a link to this post. Kiwifarms may move their sites to other providers and, in doing so, come back online, but we have taken steps to block their content from being accessed through our infrastructure.
This is an extraordinary decision for us to make and, given Cloudflare's role as an Internet infrastructure provider, a dangerous one that we are not comfortable with. However, the rhetoric on the Kiwifarms site and specific, targeted threats have escalated over the last 48 hours to the point that we believe there is an unprecedented emergency and immediate threat to human life unlike we have previously seen from Kiwifarms or any other customer before.
Kiwifarms has frequently been host to revolting content. Revolting content alone does not create an emergency situation that necessitates the action we are taking today. Beginning approximately two weeks ago, a pressure campaign started with the goal to deplatform Kiwifarms. That pressure campaign targeted Cloudflare as well as other providers utilized by the site.
Cloudflare provides security services to Kiwifarms, protecting them from DDoS and Continue reading
It’s so refreshing to find someone who understands the impact of latency on application performance, and develops a methodology that considers latency when migrating a workload into a public cloud: Adding latency: one step, two step, oops by Lawrence Jones.

Pulumi is an Infrastructure as Code (IaC) tool similar to Terraform, except that, rather than defining resources in a DSL, you defined them in a supported programming language. This means you have access to all of your chosen languages features as well as any supporting libraries...continue reading

Before founding software-defined networking startup PlumGrid and then moving to VMware when it bought his company in 2016, Pere Monclus spent almost 12 years with Cisco Systems at a time when while much of enterprise networking was still in the corporate datacenter, the shift to network virtualization and the migration to the cloud were getting underway. …

In a couple of weeks I’m taking the opportunity to broaden my leadership horizons by attending the BSA leadership course known as Philmont Leadership Challenge. It’s a course that builds on a lot of the things that I’ve been learning and teaching for the past five years. It’s designed to be a sort of capstone for servant leadership and learning how to inspire others. I’m excited to be a part of it in large part because I get to participate for a change.
Being a member of the staff for my local council Wood Badge courses has given me a great opportunity to learn the material inside and out. I love being able to teach and see others grow into leaders. It’s also inspired me to share some of those lessons here to help others in the IT community that might not have the chance to attend a course like that. However the past 3 years have also shown me the value of being a beginner at something from time to time.
Everyone is new at something. No one is born knowing every piece of information they’ll need to know for their entire lives. We learn language and Continue reading
On today’s episode of Heavy Networking, we discuss secure wireless planning and design with Jennifer "JJ Minella. JJ is the author of the book "Wireless Security Architecture." We talk about the goals for planning a wireless design, why it's worth the upfront investment, keeping operators in mind as you design your deployment, the importance of communication, design iteration, and more.

When a request at Cloudflare throws an error, information gets logged in our requests_error pipeline. The error logs are used to help troubleshoot customer-specific or network-wide issues.
We, Site Reliability Engineers (SREs), manage the logging platform. We have been running Elasticsearch clusters for many years and during these years, the log volume has increased drastically. With the log volume increase, we started facing a few issues. Slow query performance and high resource consumption to list a few. We aimed to improve the log consumer's experience by improving query performance and providing cost-effective solutions for storing logs. This blog post discusses challenges with logging pipelines and how we designed the new architecture to make it faster and cost-efficient.
Before we dive into challenges in maintaining the logging pipelines, let us look at the characteristics of logs.
Unpredictable - In today's world, where there are tons of microservices, the amount of logs a centralized logging system will receive is very unpredictable. There are various reasons why capacity estimation of log volume is so difficult. Continue reading
Welcome to Technology Short Take #159! If you’re interested in finding some links to articles around the web on topics like WASM, Git, Sigstore, or EKS—among other things—then you’ve come to the right place. I’ve spent the last few weeks collecting articles I think you’ll find useful, gleaning them from the depths of Twitter, RSS feeds, Reddit, and Slack. Enjoy, and never stop learning!
After completing the discussion of basic Kubernetes networking with a typical inter-pod traffic scenario, Stuart Charlton tackled another confusing topic: an overview of what Kubernetes services are.
