IPv4 scarcity drives widespread use of Carrier-Grade Network Address Translation, a practice in ISPs and mobile networks that places many users behind each IP address, along with their collected activity and volumes of traffic. We introduce the method we’ve developed to detect large-scale IP sharing globally and mitigate the issues that result.

Cloudflare mitigated a 12-hour DDoS attack against Moldova's Central Election Commission, blocking over 898 million malicious requests that peaked at 324,333 requests per second. This defense kept critical election infrastructure online and accessible for citizens during a critical parliamentary vote.

We identified and patched two DDoS vulnerabilities in our QUIC implementation related to packet acknowledgements. Cloudflare customers were not affected. We examine the "Optimistic ACK" attack vector and our solution, which dynamically skips packet numbers to validate client behavior.

Today over half of human-initiated traffic with Cloudflare is protected against harvest-now/decrypt-later with post-quantum encryption. What once was a cool science project, is the new security baseline for the Internet. We’re not done yet: in this blog post we’ll take measure where we are, what we expect for the coming years, and what you can do today.

Cloudflare is launching an experiment with Chrome to evaluate fast, scalable, and quantum-ready Merkle Tree Certificates, all without degrading performance or changing WebPKI trust relationships.

In Q3 2025, global Internet disruptions were caused by everything from government shutdowns to stray bullets and earthquakes. This report analyzes the traffic data behind these outages to show their real-world impact on connectivity.

We present a data-driven framework to quantify cross-layer Internet resilience. We also share a list of measurements with which to quantify facets of Internet resilience for geographical areas.

Agentic AI systems present unique security challenges. The fundamental security weakness of LLMs is that there is no rigorous way to separate instructions from data, so anything they read is potentially an instruction. This leads to the “Lethal Trifecta”: sensitive data, untrusted content, and external communication - the risk that the LLM will read hidden instructions that leak sensitive data to

Vercel Functions now supports the Bun runtime, giving developers faster performance options and greater flexibility for optimizing JavaScript workloads.

While large cloud providers hold vast troves of passive network data, analyzing them is complicated. The scale, noise, and absence of definitive ground truth all create major hurdles. Yet by carefully quantifying these constraints and finding alternative forms of evidence, meaningful insights can still emerge.

Coinciding with the ACM’s Internet Measurement Conference, the Cloudflare Research team is publishing a series of posts this week to share their research on building a more measurable, resilient, and transparent Internet. These posts will cover foundational concepts in Internet measurement, Internet resilience, cryptography, and networking.
