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/t… It describes how Cloudflare change its CDN to reduce IP address usage (which turned out to provide many other benefits!)

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-…

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-us…
Multi-User IP Address Detection

Multi-User IP Address Detection

We’ve devised novel methods to detect multi-user IP addresses, and today we’re excited to announce their integration into our global threat intelligence products. These will improve the quality of...

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) :)

This is cool. We added cdnjs on the certificate for four thousand sites that use it, and gave them a single IP to see how connections would be reused. We saw 78% fewer TLS connections to cdnjs, which means lower CPU cost and better privacy. Oddly, no clear page load time boost.

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/…

Einstein said that things should be made as simple as possible, but not simpler. However, in systems it is very common for a solution that works to be dinged because it is simple or straightforward. This comment might have to do with SOSP reviews...

Incredibly honored! Thank you @PET_Symposium. This work would not have been possible without the support from @Cloudflare Research and incredible collaborators. (@haxxpop, @jhoyla, @vavrusam, Tanya Verma, @Lekensteyn, @marwanfayed, @kheimerl, @grittygrease, @__caw__)

It’s terrific to see tech savvy members of Congress like @RepAnnaEshoo recognize the importance of secure- and private-by-design DNS (ODoH). At @Cloudflare, we’re happy to do our part in helping build a better Internet!

We have an interactive demo of OPAQUE to see how it works under the hood: opaque.research.cloudflare.c… The code behind it was developed by @claucece and @tatianaebradley with @armfazh, @thibmeu, @__caw__, and @marwanfayed. It is available on Github. github.com/cloudflare/opaque… 12/

I'm proud of the comprehensive approach that the @Cloudflare Research team is taking to help. It's an inspiring mix of academic rigor (two submitted papers this week), practical problem solving (shipping production code), and collaboration (with internal and industry partners).
