This Week in NET

In this episode, host João Tomé is joined in Cloudflare’s Lisbon office by Cloudflare Senior Research Engineer Thibault Meunier to explore a new proposal that could reshape how bots interact with the web in the age of AI.

We go into Cloudflare’s proposal of using cryptographic signatures for bots, enabling websites to verify their identity. Why is this important? As AI systems rely increasingly on online content, this standard could help build a better relationship between content creators and AI platforms.

To wrap up, Principal Engineer Kevin Guthrie walks us through the blog post “Performance measurements… and the people who love them”, which explores how teams can better measure, visualize, and communicate web performance, beyond raw metrics.

In this episode, host João Tomé is joined by Cloudflare Product Managers Nevi Shah and Dina Kozlov to go into the world of MCP (Model Context Protocol), and why it’s gaining traction fast.

We explore what MCP is, why it matters now, and how developers can easily spin up their own MCP servers on Cloudflare. The episode includes live demos, practical use cases, and a look at how companies like Stripe, PayPal, and Anthropic are getting involved.

We also cover the latest from the AI and agent ecosystem, including announcements from Microsoft Build, Google I/O, OpenAI’s new responses API, and Anthropic’s growing MCP support.

To wrap things up, Nevi and Dina answer a round of fast questions:

We also highlight recent posts on the Cloudflare blog.

In this episode of This Week in NET, we sit down at Cloudflare’s Lisbon office in Portugal with one of the Internet’s original architects: Geoff Huston, Chief Scientist at APNIC (the Asia-Pacific Internet registry).

From helping build Australia’s first Internet backbone to now shaping global conversations on resilience, routing security, and cryptography, Geoff shares a rare, unfiltered view of how the Internet grew, and where it’s struggling.

We dive into the critical topics shaping the next decade: Internet resilience, RPKI, the evolution of DNS, QUIC, post-quantum cryptography, and the rise of AI-driven protocols like MCP.

Join us for a candid conversation with someone who has seen — and helped shape — the Internet as we know it, and who loves telling stories about how it all began — from silicon chips to the age of the Internet and AI.

Mentioned blog posts (in the intro):

In this week’s episode, we talk about DDoS attacks and their sharp rise in recent months. We also start with a quick look at some Internet trends tied to the announcement of the new pope.

To guide us through the world of distributed denial-of-service (DDoS) attacks, host João Tomé is joined by our DDoS expert, Omer Yoachimik.

We go into the latest data from our Q1 2025 DDoS Threat Report, which reveals a 358% year-over-year increase in DDoS attacks — and explore what’s driving that surge. The report also includes late-breaking data from a hyper-volumetric campaign observed in April 2025, featuring some of the largest attacks ever publicly disclosed.

We also cover which industries and countries are being targeted more often, like gaming and financial services, and discuss why that might be the case.

Targeted by 20.5 million DDoS attacks, up 358% year-over-year: Cloudflare’s 2025 Q1 DDoS Threat Report

In this week's episode, we talk about Internet disruptions — focusing on the recent major power and Internet blackout, while also reviewing the broader Internet disruptions of Q1 2025.

Host João Tomé shares his firsthand experience during the blackout in Lisbon, Portugal, and how an old battery-powered FM radio came to the rescue. He’s joined by David Belson, Head of Data Insights at Cloudflare.

In Q1 2025, Internet disruptions were driven by cyberattacks, cable cuts, and natural disasters like the Myanmar earthquake and California wildfires. There were no government-directed shutdowns, making Q1 a rare quarter.

In this week's episode, we continue exploring AI, agents, developers, and how AI is helping developers, and turning more people into developers. For that, host João Tomé chats in the library of our London office with Sunil Pai, Principal Systems Engineer, who’s building AI agents at Cloudflare.

Next, recorded two weeks ago at our Connect event in London, we talk with Ashley Peacock, a British engineer and Cloudflare Dev Expert who also wrote the book “Serverless Apps on Cloudflare”. We discuss building with Cloudflare, the challenges that come with AI, and whether making things too easy for new developers could create issues — and what lies ahead for the dev community.

We also bring back our short segment “Social Love”, highlighting the amazing feedback Cloudflare’s Developer Week got online.

To wrap up, we recap the week: YouTube celebrated 20 years since its first video, and we highlight our recent blog posts — the Q1 2025 Internet disruption summary, Kelly Russell on why she joined as Chief People Officer, and Mark Jenkins on why he came to build world-class partnerships in EMEA.

Mentioned content:

This episode is all about our second innovation week of the year: Developer Week. Host João Tomé is joined in person at Cloudflare’s London office by Ricky Robinett, VP of Developer Relations, and Craig Dennis, Developer Educator.

There’s a lot to go through — new tools and announcements launched during this April week. The vibe in the developer world, with AI, agents, and code-first energy, is contagious. More people, even non-developers, are now empowered to build their own tools and applications.

We go over announcements that reinforce why Cloudflare is the place where builders should create AI agents. We’ve also added observability tools, made deploying existing applications to Cloudflare frictionless, enhanced our platform for enterprise users, and introduced updates that make it the future of global data experiences.

Topics such as Workflows, Hyperdrive, AutoRAG, and support for MCP (Model Context Protocol) are discussed. We also explain how MCP introduces a new standard for how LLMs interface with the world. Other highlights include Realtime, RealtimeKit, and much more.

In this week's episode, we set the stage for Cloudflare’s second innovation week of the year — Developer Week. Host João Tomé is joined by Ricky Robinett, VP of Developer Relations, to preview what to expect when Developer Week kicks off on April 7, with announcements running through April 11, 2025. There we also mention how developers can now build and deploy remote MCP servers to Cloudflare.

Next, Craig Dennis, Developer Educator at Cloudflare, explains what Workers — our developer platform — is all about, and why even non-developers should try building with it.

We also honor the American network engineer Dave Täht, who passed away this week. Tom Strickx, Principal Network Engineer at Cloudflare, shares how Dave’s contributions helped build a better Internet. Without his engineering and advocacy work, FQ-CoDel wouldn’t exist, and modern low-latency networking, from Wi-Fi and Starlink to video conferencing, would likely be far worse today.

Finally, we round up some recent blog highlights: from an April 1 launch to a deep technical post. And also John Graham-Cumming’s journey from programmer and CTO to joining Cloudflare’s board of directors — Dane Knecht, formerly SVP of Emerging Technology and Incubation, has been named Cloudflare’s new CTO.

Security Week: in review

We’re back with new episodes in 2025, kicking off this week with a Security Week teaser. Host João Tomé is joined by Michael Tremante, Sr. Director of Product Management, to discuss what to expect from our first innovation week of the year, starting next week. They also explore the security landscape in 2025 and the importance of simplicity.

Next, we talk about our new wall of entropy—a wave machine installation in the reception of our Lisbon office, contributing to Internet security. Caroline Quick, Head of Real Estate & Workplace Operations, shares how the project came to life and why waves are the perfect fit for our Portugal office.

Finally, in honor of Pi Day (March 14), Thibault Meunier, an engineer from our Research team, explains why Pi (π ≈ 3.14159…) is a fundamental mathematical constant, shaping engineering, computing, and quantum physics.
