New TCP resets and timeouts dataset on Cloudflare Radar surfaces connection tampering, scanning, DoS attacks, and more. cfl.re/4dNqlLt
@Cloudflare Very proud to have worked on this with @ramakrishnan13s @marwanfayed @DistributedDave @kkevsterrr @henri_merino @grittygrease and many others
🎉 Join us for a special segment celebrating 50 years of the “TCP paper”! Our experts dive into why TCP is crucial for the Internet’s evolution and its future. Featuring @mnot, @marwanfayed, and @SimmerVigor. Don’t miss it! #TCP #Internet 🌐✨ cfl.re/4aN6BFk
Congrats to the winners! ANRP helps bridge two communities that advance state of the art with two different consensus processes. A wide-subject and engaging set of nominees this year. One can only imagine the things that 2024 will bring.

This week's paper is "The Ties that un-Bind: Decoupling IP from web services and sockets for robust addressing agility at CDN-scale": micahlerner.com/2022/01/13/the… It describes how Cloudflare change its CDN to reduce IP address usage (which turned out to provide many other benefits!)
Looking ahead to post-quantum-safe TLS! Also a reminder that congestion control is subtle, powerful, well-tuned... and still a hot research topic after 40 years. "Respect!"

Today's blog post by @GVasilis and @marwanfayed goes into detail about just how good this guess can be. The results show that Cloudflare has the lowest latency globally of any CDN. And now anyone can validate that claim without running a single scan. blog.cloudflare.com/look-ma-no-pro…
Spaces open for PhD research interns, too! blog.cloudflare.com/kicking-off-cl…
This post by interns Nate Sales and Alex Chen explains how we combine our knowledge of the Internet from public datasets with device-reported information to inform other teams at Cloudflare which source IPs are single-user and which are multi-user. blog.cloudflare.com/multi-user-ip-…
Happy to share that I worked on these connection coalescing experiments as a Cloudflare intern this year with some amazing colleagues (@SulemanAhmadd, Jonathan Hoyland) and mentors (@grittygrease, @marwanfayed) :)

Even more from #CloudflareResearch🔬 today. This time we have a deep dive into our paper at ACM SIGCOMM about disentangling the mess of conventions around IP addresses, hostnames, and sockets. Plus, two posts about the future of our "favorite" authentication mechanism: passwords.
Had the great privilege of interviewing @marwanfayed - so knowledgeable and so humble. We discussed everything from academia vs. industry, to what research looks like, to solving the backhaul problem. Give a listen: lnkd.in/emu-u2Bg
The architecture of the Internet is fundamentally changing. Lightweight semi-trusted proxies are being used to add privacy to lower layers. Led by @sudheesh001, we published a paper at PETS this year analyzing how ODoH helps make DNS more private. petsymposium.org/2021/files/pap…
Sometimes Research is especially rewarding. Kudos to team for getting ZKP not just in the browser, but also running at under 10 seconds. blog.cloudflare.com/introducing-ze…
