More than a decade ago I published tons of materials on a web site that eventually disappeared into digital nirvana, leaving heaps of broken links on my blog. I decided to clean up those links, and managed to save some of the vanished content from the Internet Archive:
I also updated dozens of blog posts while pretending to be Indiana Jones, including:

The idea of serverless is to allow developers to focus on writing code rather than operations — the hardest of which is scaling applications. A predictably great deal of traffic that flows through Cloudflare's network every year is Black Friday. As John wrote at the end of last year, Black Friday is the Internet's biggest online shopping day. In a past case study, we talked about how Cordial, a marketing automation platform, used Cloudflare Workers to reduce their API server latency and handle the busiest shopping day of the year without breaking a sweat.
The ability to handle immense scale is well-trodden territory for us on the Cloudflare blog, but scale is not always the first thing developers think about when building an application — developer experience is likely to come first. And developer experience is something Workers does just as well; through Wrangler and APIs like Workers KV, Workers is an awesome place to hack on new projects.
Over the past few weeks, I've been working on a sample open-source e-commerce app for selling software, educational products, and bundles. Inspired by Humble Bundle, it's built entirely on Workers, and it integrates powerfully with all kinds of first-class modern Continue reading
In this week's IPv6 Buzz episode, Ed and Tom talk discuss the impact that service provider deployment of Carrier Grade NAT (CGN) has had on the overall adoption of IPv6. Our guests are Kevin Myers and Nick Russo. Kevin and Nick have both worked with CGN and IPv6, and Nick is designing an IPv6 training course on Pluralsight.

The Internet is for everyone – a critical lifeline that can uplift communities. But only if we go beyond Internet access and bridge the knowledge gap that continues to persist: the gap between those who have the knowledge and skills to use the Internet to empower themselves and their communities and those who don’t.
To address this divide, the Internet Society Foundation recently awarded over $1 million in digital skills development grants to eight innovative projects in Bangladesh, Colombia and Senegal. In its pilot year, the Strengthening Communities, Improving Lives and Livelihoods (SCILLS) grant programme aims to expand economic growth, improve health outcomes, and increase educational opportunities by supporting individuals and communities to more knowledgeably and skillfully use the Internet.
The Internet Society Foundation was established in 2019 to support the positive difference the Internet can make to people everywhere. The Foundation awards grants to Internet Society Chapters/Special Interest Groups (SIGs) as well as nonprofit organizations and individuals dedicated to providing meaningful access to an open, globally-connected, secure, and trustworthy Internet for everyone.

Hello my friend,
Just recently we have started discussion about the tools about the performance troubleshooting in networks. One of the questions we were asked afterwards was, how to programatically get your public IP? Well, that is interesting one.

Yes, and that was a question we’ve started this blogpost with is about that. How can we rely the automation tools by troubleshooting? How can we get our IP to make any diagnostics? You will see some things right in this blogpost
Our network automation training has two faces: either live or self-paced. So you can choose yourself, what works better for you. On our side, we guide you from the foundation of the automation for the small networks till advanced automation use cases in big data centres, service providers, and clouds. You will lean how to structure the data using YANG modules, how to serialise it using JSON, XML, Protocol Continue reading
It’s amazing how far you can get if you keep doing something for a long-enough time. In a bit over 10 years (the initial versions of the earliest still-active webinars were created in October 2010), we accumulated over 300 hours of online content available with ipSpace.net subscription, plus another 130 hours of online course content.
Obviously I couldn’t have done that myself. Thanks a million to Irena who took over most of the day-to-day business a few years ago, dozens of authors, and thousands of subscribers who enabled us to make it all happen.

None of us can stop thinking about how 2020 has changed the way we go about our daily tasks. Going to school, going to the store, going out to eat — going anywhere at all. But now, for the first time, we are not even going to work! Everyone has been pushed to work from home. This change has a wide-ranging set of variables that need to be addressed, from the business limits on resources for connectivity to the employee’s limits on remote resources of space, privacy, and uninterrupted concentration.
The overnight reliance on remote, personal, shared services for connectivity from the worker to the corporation has forever put an end to the idea of a security perimeter. Zero Trust Architecture (ZTA) has moved from being an academic discussion to a persistent customer requests for solutions. This shift is furthered by the timely release of the US National Institute of Standards and Technology’s NIST Special Publication 800-207 ZTA Guide. At the same time, we now see numerous security industry vendors claiming their products will provide Zero Trust.
Naturally, many VMware customers want Continue reading
From working in unbelievable environments to dealing with unexpected bugs, the longer that you do networking for a career the more likely it is that you have a story or two from the trenches to share. Listening to other’s adventures can serve both as a cathartic release and as a warning for roads to leave untraveled. In today’s episode we talk with some experienced engineers about their stories. If nothing else, you as the listener can have some laughs at our expense. Enjoy!
Thank you to Bluecat Networks for sponsoring today’s episode. Bluecat is putting together some great content and a great community surrounding the topics of DNS, DHCP, and IPAM.

One of the great arts of software engineering is making updates and improvements to working systems without taking them offline. For some systems this can be rather easy, spin up a new web server or load balancer, redirect traffic and you’re done. For other systems, such as the core distributed data store which keeps millions of websites online, it’s a bit more of a challenge.
Quicksilver is the data store responsible for storing and distributing the billions of KV pairs used to configure the millions of sites and Internet services which use Cloudflare. In a previous post, we discussed why it was built and what it was replacing. Building it, however, was only a small part of the challenge. We needed to deploy it to production into a network which was designed to be fault tolerant and in which downtime was unacceptable.
We needed a way to deploy our new service seamlessly, and to roll back that deploy should something go wrong. Ultimately many, many, things did go wrong, and every bit of failure tolerance put into the system proved to be worth its weight in gold because none of this was visible to customers.
Our goal Continue reading
For many in the African region, Internet interruptions or service degradations occur frequently, which results in a disjointed Internet experience. In order to help improve this experience, we need to track and measure various Internet characteristics through network telemetry. This data can help to identify infrastructure and traffic issues and can provide key information to help decision makers decide where infrastructure investment and policy change might need to be made.
However, as shown by a survey carried out by AFRINIC, the Regional Internet Registry (RIR) for Africa, in 2019, Internet measurement is not a common practice in the African region. This is largely due to a scarcity of deployed measurement tools, platforms and equipment, a lack of awareness in the subject, and the lack of relevant skills to carry out the measurement tasks. The shortage of measurement equipment in African countries makes it very challenging to accurately determine the problem areas that need to be addressed in order to improve Internet reliability and resilience in Africa.
Collaborative Measurements
Assessing the resilience of the Internet is a key component of the Internet Society’s work on Measuring the Internet. To help identify the causes of Internet interruptions and service degradations, we Continue reading
