The Value of Concise Communication

When I first started working at Tech Field Day, one of the things that I struggled with was writing. Sure, I’d been writing blog posts for almost three years at that point. But what I really had issues with was my communication style through email. Every message became a small blog post unto itself. I spent more time answering every possible question and providing way more information than was needed. Luckily, Stephen Foskett helped me figure out that concise communication was critical. That lesson has grown on me through the current day.

Working With a Watch

I want you to think back to an interaction that you’ve had recently where you were talking to someone. Maybe you were asking them a question or looking for them to provide an opinion about something. How much did they talk? Was it a short pointed answer? Or did it feel as if it was going on forever? It’s something I’ve noticed recently with people I talk to in real life. The discussions aren’t short and focused. Instead they carry a lot of extra information and exposition that makes things take far too long.

Yes, I know the irony of that statement for Continue reading

MANRS for Enterprise Customers

In October 2023, I was talking about Internet routing security at the DEEP conference in Zadar, Croatia. After explaining the (obvious) challenges and the initiatives aimed at making Internet routing more secure (MANRS), I made my usual recommendation: vote with your wallet. However, if you’re a company in Croatia (or Slovenia, or a number of other countries), you’re stuck.

While ISPs in Croatia might be doing a great job, none of them is a MANRS participant1, so we don’t know how good they are. The situation is not much better in Slovenia; the only ISPs claiming to serve Slovenia are Anexia (a cloud provider) and Go6 Institute, the small network operated by my good friend (and True Believer in IPv6 and MANRS) Jan Žorž. Moving further north, there are decent choices in Austria, and tons of options in Germany or Switzerland. I must be living in a truly thrifty part of Europe.

Standing up for the open Internet: why we appealed Italy’s “Piracy Shield” fine

At Cloudflare, our mission is to help build a better Internet. Usually, that means rolling out new services to our millions of users or defending the web against the world’s largest cyber attacks. But sometimes, building a better Internet requires us to stand up against laws or regulations that threaten its fundamental architecture.

Last week, Cloudflare continued its legal battle against "Piracy Shield,” a misguided Italian regulatory scheme designed to protect large rightsholder interests at the expense of the broader Internet. After Cloudflare resisted registering for Piracy Shield and challenged it in court, the Italian communications regulator, AGCOM, fined Cloudflare a staggering €14 million (~$17 million). We appealed that fine on March 8, and we continue to challenge the legality of Piracy Shield itself. 

While the fine is significant, the principles at stake are even larger. This case isn't just about a single penalty; it’s about whether a handful of private entities can prioritize their own economic interests over those of Internet users by forcing global infrastructure providers to block large swaths of the Internet without oversight, transparency, or due process.

What is Piracy Shield?

To understand why we are fighting this, it’s necessary to take a step back Continue reading

netlab Graphs with Multi-Access Links

A netlab user wanted to create a nice-looking topology graph from a simple topology connecting a few devices to a broadcast (multi-access) link. I don’t have his exact topology, so we’ll use this one (skipping the details like setting device types)

nodes: [ r1, r2, h1, h2 ]

links:
- r1-r2
- interfaces: [ r1, r2, h1, h2 ]

This is what GraphViz generates based on netlab’s description of the lab topology:

Network Device Telemetry Protocols with Dinesh Dutt

Whenever I’m ranting about vendors changing their data models or APIs with every other release, there is inevitably a vendor engineer chiming in, saying, “Life would be so much better if the customers wouldn’t insist on doing screen scraping for the last 50 years.”

While some of that screen scraping is pure inertia, we sometimes have good reasons to do it rather than use protocols like NETCONF, gNMI, or protobufs. In Episode 205 of Software Gone Wild, I’m discussing some of those reasons and exploring the gap between vendor theory and reality with Dinesh Dutt, who is unlucky enough to have become the world’s foremost expert on crappy network telemetry.

From legacy architecture to Cloudflare One

For a network engineer, the cutover weekend is often the most stressful 48 hours of their career. Imagine a 30,000-user organization attempting to flip 1,000+ legacy applications from fragmented VPNs to a new architecture in a single window. The stakes are immense: a single misconfigured firewall rule or a timed-out session can halt essential services and lead to operational gridlock.

This "big bang" migration risk is the single greatest barrier to Zero Trust adoption. Organizations often feel trapped between an aging, vulnerable infrastructure and a migration process that feels too risky to attempt.

Cloudflare and Technology Solutions Provider CDW are changing this narrative. We believe that a successful transition to SASE (Secure Access Service Edge) shouldn't feel like a leap into the dark. By combining Cloudflare’s global Zero Trust platform with CDW’s experience navigating the industry’s most complex deployment failures, we provide the strategic roadmap to de-risk the journey. We don't just move your "plumbing" — we ensure your legacy debt is transformed into a modern, agile security posture without the downtime.

Leveraging partner expertise to avoid migration traps

Traditional migrations often fail because they treat the network as simple plumbing rather than a complex ecosystem of applications. Without a Continue reading
