Cloudflare Research is building a global consensus service called Meerkat that uses a new consensus algorithm called QuePaxa. We plan to use Meerkat to build a strongly consistent, fault-tolerant key-value store, and other applications.
By applying symbolic execution and the Z3 theorem prover to BPF bytecode, we’ve automated the generation of malware trigger packets, cutting analysis time from hours to seconds.
Workers VPC Services enter open beta today. We look under the hood to see how Workers VPC connects your globally-deployed Workers to your regional private networks by using Cloudflare's global network, while abstracting cross-cloud networking complexity.
A BGP “zombie” is essentially a route that has become stuck in the Default-Free Zone (DFZ) of the Internet, potentially due to a missed or lost prefix withdrawal. We’ll walk through some situations where BGP zombies are more likely to rise from the dead and wreak havoc.
Cloudflare has been tracking and comparing our speed with other top networks since 2021. Let’s take a look at how things have changed since our last update.
Cloudflare was recently contacted by researchers who discovered a broadcast amplification vulnerability through their QUIC Internet measurement research. We've implemented a mitigation.
Multi-Path TCP (MPTCP) leverages multiple network interfaces, like Wi-Fi and cellular, to provide seamless mobility for more reliable connectivity. While promising, MPTCP is still in its early stages,
Cloudflare is the fastest provider in 44% of networks around the world for 95th percentile connection time. Let’s dig into the data and talk about how we do it
Today, we’re excited to announce that a free version of Cloudflare’s network flow monitoring product, Magic Network Monitoring, is now available to all Enterprise Customers
Introducing Magic Cloud Networking, a new set of capabilities to visualize and automate cloud networks to give our customers secure, easy, and seamless connection to public cloud environments
This is our story of what we learned about the connect() implementation for TCP in Linux. Both its strong and weak points. How connect() latency changes under pressure, and how to open connection so that the syscall latency is deterministic and time-bound
Meet the smartest member of the Cloudflare network team that helps keep you online no matter what happens to the Internet underneath us
We want to give you a behind the scenes look at how we have evolved the core mechanism of our product–namely, exactly how it kicks in to queue traffic in response to spikes
We run a wide fleet of machines on the Cloudflare global network. This post describes how we minimize customer disruption during large-scale machine reboots using math!
Ping developers clearly put some thought into that. I wondered how far they went. Did they handle clock changes in both directions? Are the bad measurements excluded from the final statistics? How do they test the software?
Cloudflare’s mission is to help build a better Internet for everyone, and Orpheus plays an important role in realizing this mission everyday.
We are pleased to announce that Cloudflare is now connected to over 12,000 Internet networks in over 300 cities around the world
There’s an important debate happening in Europe that could affect the future of the Internet. The European Commission is considering new rules for how networks connect to each other on the Internet.
