If you're still trying to get to grips with HTTP/3 and QUIC, this blog post includes a list of all of my Cloudflare TV segments with various deep dives and special guests.
A Last Call for QUIC, a giant leap for the Internet. cfl.re/2HrS22d
A massive effort from many engineers across multiple teams. Each day we've replaced planks on the fleet of Theseus composed of the ingress proxy (TLS, QUIC and more), and the brain (FL). Our spotters in the crows nest have shouted land ahoy. The beaches are full of rustaceans.
Here's why we’ve replaced the original core system in Cloudflare with a new modular Rust-based proxy, replacing NGINX. cfl.re/4h1Jhst #BirthdayWeek
Super excited about this. More intel. Deeper insights. Snappier user jounrneys. Happier customers.
The free tier on Cloudflare should be better than paid subscriptions elsewhere. Making sure you're getting the most out of Cloudflare starts with measurement. blog.cloudflare.com/the-rum-diarie…
As a MASQUE enthusiast, I approve
We are excited to add QUIC obfuscation for WireGuard, aimed at helping users bypass firewalls and censorship. This new feature is now available on all desktop platforms. The Android & iOS apps will include QUIC obfuscation in future releases. Read more here:…
We’ve deployed MoQ in production! Long time coming and first step to broader adoption
Media over QUIC (MoQ) is a new IETF standard that resolves this conflict, creating a single foundation for sub-second, interactive streaming at a global scale. cfl.re/4fLcas0
MoQ (media over quic) is a new protocol for streaming — basically pub/sub for media you can check it out running in production here → moq.dev/publish/ and the blog post (very classic cloudflare deepdive you can follow style). @rrnn is a top tier story teller

I'm excited to announce I'll be at gRPC Conf on August 26 2025 to present how Cloudflare built its gRPC support first launched in 2020, and how we've been adding gRPC over HTTP/3 support lately. Session details at: grpcconf2025.sched.com/event/26BMY/br…
The AI Preferences (AIPREF) Working Group began work this year to make it easier to express how AI models should use Internet content. Work is well underway on a compressed timeline for delivery. Read the latest progress update and the path ahead: ietf.org/blog/ai-pref-p…

Bots can start authenticating to Cloudflare using public key cryptography, preventing them from being spoofed and allowing origins to have confidence in their identity. cfl.re/40xTGVx
An open Internet depends on a model that incentivizes great content to continue to be published. Proud to partner with some of the best publishers and AI services to launch a new model built that rewards high-quality material in a new AI era.
Cloudflare is making it easier for publishers and content creators of all sizes to prevent their content from being scraped for AI training. Here's how: cfl.re/4l2cXqp
Orange Meets, our open-source video calling web application, now supports end-to-end encryption using the MLS protocol with continuous group key agreement. cfl.re/45Cji79

Client side packet loss metrics from a customer at scale moving from Twilio to Cloudflare TURN
Marek was one of the people responsible for first putting Cloudflare on my radar back in 2015. Mostly via deep yet accessible blogs. Been a pleasure to work alongside him since 2018. Although I think we only met in-person twice, the internal chats were always amazing. TTFN MM
Today, after almost 12 years, is my last day at Cloudflare. I've seen the company grow from 60 to 5,000 people. I helped bootstrap things like DDoS, Spectrum, Cloudchamber, and Egress, and wrote hundreds of internal and dozens of public blog posts. It has been an amazing journey.
