Network performance update: Developer Week 2025

As the Internet has become enmeshed in our everyday lives, so has our need for speed. No one wants to wait when adding shoes to our shopping carts, or accessing corporate assets from across the globe. And as the Internet supports more and more of our critical infrastructure, speed becomes more than just a measure of how quickly we can place a takeout order. It becomes the connective tissue between the systems that keep us safe, healthy, and organized. Governments, financial institutions, healthcare ecosystems, transit — they increasingly rely on the Internet. This is why at Cloudflare, building the fastest network is our north star. 

We’re happy to announce that we are the fastest network in 48% of the top 1000 networks by 95th percentile TCP connection time between November 2024, and March 2025, up from 44% in September 2024.

In this post, we’re going to share with you how our network performance has changed since our last post in September 2024, and talk about what makes us faster than other networks.  But first, let’s talk a little bit about how we get this data.

It’s happened to all of us Continue reading

Network performance update: Birthday Week 2024

When it comes to the Internet, everyone wants to be the fastest. At Cloudflare, we’re no different. We want to be the fastest network in the world, and are constantly working towards that goal. Since June 2021, we’ve been measuring and ranking our network performance against the top global networks. We use this data to improve our performance, and to share the results of those initiatives. 

In this post, we’re going to share with you how our network performance has changed since our last post in March 2024, and discuss the tools and processes we are using to assess network performance. 

Digging into the data

Cloudflare has been measuring network performance across these top networks from the top 1,000 ISPs by estimated population (according to the Asia Pacific Network Information Centre (APNIC)), and optimizing our network for ISPs and countries where we see opportunities to improve. For performance benchmarking, we look at TCP connection time. This is the time it takes an end user to connect to the website or endpoint they are trying to reach. We chose this metric to show how our network helps make your websites faster by serving your traffic where Continue reading
