Real-time visibility

Real-time logs, streamed from our edge, give near-instant visibility into traffic trends, performance, potential problems, and threats.

Insights you can use

Logs provide an important resource for troubleshooting connectivity problems, pinpointing configuration areas that could use performance tuning, and identifying the causes of service disruptions.

Logging provider integrations

Instantly stream your log files to a logging provider of your choosing, and dig into any aspect of a request or response to diagnose problems and understand how your customers are engaging with your app.

Support for agile DevOps

The days of agile development efforts getting stuck in release queues are over. With our real-time visibility and control we integrate into your existing workflows so you can deploy new software or feature enhancements weekly, daily, or even multiple times a day.

Fastly’s fully configurable CDN enables you to change content quickly, even event-driven content. Easily adjust your configuration settings via an API and roll back changes as needed without having to reach out to Professional Services.

Rapid content changes

Fastly’s fully configurable CDN gives customers fine-grained control over how their content is cached.


Our full-featured API makes it easy to change configuration settings - customers can instantly purge stale content, reset time-to-live, clear cache or turn on new features all through an API call.They can create custom caching rules, upload them to our POPs and activate/deactivate them on the fly all without having to engage with Professional Services.

Stress-free rollbacks

We lock versions of services already activated making rollbacks hassle-free and facilitating easier version control.

Built-in security

Our DDoS, next-gen WAF and TLS offerings provide organizations protection and control, without sacrificing performance and velocity. We have built security into the fabric of our platform, alongside performance, providing developers and security operations teams with a fast, safe environment to create, build, and run modern applications.

Faster purging

Our software-defined network gives us incredible performance gains when it comes to purging, which is core to CDNs. We can purge stale content in 150 ms globally. Coupled with batch purging and surrogate key purging, customers can effectively cache highly dynamic content at the edge with the peace of mind that it can be purged from cache globally in milliseconds.

Higher cache hit ratios

Our modern network design includes fewer, more powerful POPs, allowing customers to cache more at the edge for longer, including rapidly changing content like inventory, pricing or news. This translates into better cache hit ratios meaning web and mobile users get quicker response times and downloads.

Better performance

Dynamic site acceleration (DSA) features come standard for speedy content delivery that makes a positive impact on conversion and retention rates, Search Engine Optimization (SEO), and ad revenue.

Savings and efficiencies

Our configurable CDN allows customers to save on costs. Because we can purge so quickly, customers can cache more at the edge, even API responses. This minimizes trips to origin, reducing infrastructure and egress costs. Also, full configurability means changes are automatically passed from development to production without having to engage Professional Services.
