For businesses that demand seamless Internet video playback, high-performance websites or far-reaching digital file distribution, CenturyLink's Content Delivery Network helps deliver content faster by leveraging our scalability, global footprint and proven customer service.
Our CDN contains racks of powerful caching servers that are loaded with high-capacity storage and locally connected to the Internet through a distributed set of Points of Presence (PoPs). This approach enables organizations to deliver deep content like videos, images, and stylesheets from a global network. By pushing content to users from the servers closest to them, instead of from a centralized location, we significantly improve the user experience, reduce load times and boost the overall performance of web and other Internet-based apps.
CenturyLink is trusted by many of the biggest names in global media to deliver content because we provide the performance they need, and that customers expect in the ever-increasingly competitive landscape.
Provide a rich experience for on-demand and live linear streaming. CenturyLink's global CDN is an end-to-end solution that offers the performance and scale you need for content acquisition, storage and encoding, to multi-device delivery around the world. Our CDN is architected for high capacity, high availability and low latency, delivering an exceptional Quality of Service (QoS).

A Content Delivery Network can offer a better user experience by helping websites with wide geographic relevance to deliver content faster. Everyone knows latency is the enemy. Closing the gap between content and users is the most important benefit a CDN offers to both you and your customers.
When broadcast and video websites needed an effective platform to deliver high-quality content online, an enterprise streaming provider sought a CDN with a global footprint that could offer excellent performance when faced with large amounts of traffic, as well as responsive customer service.
CenturyLink's CDN offers Secure Socket Layer (SSL), an important security feature that establishes an encrypted link between a web server and a browser. Enabling an SSL Private Certificate on a CDN allows for a secure connection between the edge servers and the user accessing the content.
