Fastly CDN: Deliver fast, personalized experiences globally

The API is organized into collections of endpoints that allow manipulation of objects related to Fastly services and accounts.

Can be used to support TLS certificate management for non-SNI clients, to support custom cipher suites or IP-to-service pinning, or to help manage zero-rated billing endpoints.

Fastly allows you embed custom metadata or ad markers about a stream into video segments at specified time instances.

Fastly’s dynamic site acceleration comes standard for speedy content delivery that makes a positive impact on conversion and retention rates, SEO, and ad revenue.

Deliver@Edge gives you direct access to content delivery, control and edge logic capabilities.

Fastly gives you complete control over HTTP headers so you can determine how you want your content served, including the ability to send one set of instructions to your Fastly services and another set of instructions to downstream caches, proxies or browsers.

Fastly does not charge separately for web vs. streaming content nor for features like instant purging that make supporting dynamic and event-driven content possible. We provide one programmable service that optimizes all types of HTTP content.

Allows you to have your IP spaces announced, routed, and served by Fastly infrastructure for use with production services.

Content expiration is controlled via Time to Live (TTL) settings you configure that work as timers on your cached content.

Remove your cached content worldwide on demand, within milliseconds, when your dynamic or event-driven content changes.

To help you tune the performance of your Fastly services, we support real-time log streaming of data that passes through Fastly.

Allows you to mark content as outdated (stale) instead of permanently purging and thereby deleting it from Fastly's caches.

A surrogate key allows you to selectively purge related content.

Fastly's globally distributed network was built to absorb Distributed Denial of Service (DDoS) attacks.

Fastly can automatically detect and, in real time, route around transient connection problems that occur when fetching content from your origin servers or when delivering content to end users from Fastly's edge cloud.

Fastly can encrypt videos packaged into HLS and MPEG-DASH and supports multiple Digital Rights Management (DRM) technologies.

Grace mode shields application servers by instructing Deliver@Edge to continue to serve stale or expired (but likely still valid) content to end users for a set amount of time.

Fastly supports a variety of Transport Layer Security (TLS) services that allow websites and applications to serve traffic over HTTP Secure (HTTPS), providing added privacy and data security for your services and end users.

Fastly caches your content close to end users throughout the world so it can be served more quickly and reduce load and cost of your origin services

Fastly can compress your content in real-time at the edge, providing snappier end user experiences and off loading content compression from your origin services.

You can designate a Fastly point of presence (POP) to serve as a shield for your origin servers, enabling increased cache hit rates for your Fastly services and potentially protecting your origin servers from unexpected spikes in requests.

Fastly's request collapsing feature groups those requests and fulfills them together when it receives the refreshed content from your origin.
