It’s time your CDN did more. If reliability, speed, and the freedom to customize delivery is critical for you, then Fastly’s CDN with real-time observability, programmatic control and baked-in security helps you deliver the dynamic experiences today’s users demand.
Boost performance and scale
Cache a wider range of content, including dynamic and event-driven content, for enhanced speed and personalization. Our network architecture with hyper-connected, high-capacity POPs and lightning-fast purging with Instant Purge™, ensures more content remains cached, improving performance, scale and user experience.
Reduce delivery costs
Serving more content from cache reduces trips to the origin, reducing egress costs. Use Fastly as an Origin Shield for further cache efficiency. With Fastly’s network, ensure availability and uptime with protection from traffic spikes and attacks. Full configurability means changes are automatically passed from development to production.
Improve developer productivity
Our highly configurable network offers developers real-time configuration control, comprehensive APIs, stress-free rollbacks, and real-time logs for quick issue resolution, reducing dependence on professional services and release queues. Seamless integration with CI/CD cycles and DevOps tools enhances workflows and developer satisfaction.
Features
Modern architecture, powerful POPs
Our modern network design including fewer, more powerful POPs, and our Instant Purge™ capabilities enable caching more at the edge for longer, including rapidly changing content like inventory, pricing or breaking news.

Real-time visibility
Fastly's real-time log streaming offers instant visibility into traffic, performance, threats, and troubleshooting. Stream logs to your preferred logging provider and dig requests or responses to diagnose problems and understand how your customers are engaging.
"We couldn't gain the confidence of our editorial team to place a CDN in front of our website unless we could clear content from the cache instantly. If breaking news happens and it isn't on our site within seconds, visitors will go elsewhere. With Fastly, updates are reflected on our site pages within milliseconds and we've seen a 20% improvement in time to first byte around the world."
Matthew O'Brien
Software Architect
“The savings we get by using Fastly for our media transfers is enormous. We do more than a petabyte per month of data transfers. If we left that to our cloud provider and delivered it from object storage, it would cost hundreds of thousands of dollars per month. Plus, there's compute savings because we maintain a good cache hit ratio with our API.”
Brian Benns
Senior Site Reliability Engineer
“It's DevOps easy. It's DevOps friendly. It was built for people within IT. You can API anything you need. You can use Terraform for anything that you want. All the data is there at your fingertips. Configuration is easily changed and tracked. There are so many things that are just built by people that obviously love HTTP and for people that use HTTP for their living.”

CDN’s are an essential tool to enhance the performance of websites and applications and guarantee the best user experiences. They help to reduce latency, enhance performance, improve security, reduce costs, increase scalability, boost site visibility, and improve site availability.
How can a CDN improve load time?
CDNs can dramatically decrease your website’s load time through several key capabilities. An effective CDN minimizes the delay between a data request and the delivery by caching and storing your website's content on servers close to your customers, which means less waiting time. With content served from local edge servers, your customers will spend less time waiting for pages and assets to load, including those with high-bandwidth, media-rich content, leading to higher satisfaction levels thanks to the smoother user experience.
What should you look for in a CDN?
