Reliable, Secure, High-Performing Content Delivery and FOOTPRINT® Transmission Services

For businesses that demand seamless Internet video playback, high-performance websites or far-reaching digital file distribution, Lumen's Content Delivery Network helps deliver content faster by leveraging our scalability, global FOOTPRINT® technology 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.

Lumen 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.

Content Delivery Network leverages our scalability, global FOOTPRINT® technology and proven customer service.
Content Delivery Network acclerates delivery of web content.

Web Acceleration

Increase performance of sites and applications by offloading the delivery of static objects to our CDN Services. Use caching servers deployed in data centers around the globe to host images, stylesheets and other static content. This approach reduces download times, and keeps other resources focused on more dynamic workloads. Supports HTTP or HTTPS protocols.

Streaming Media Delivery

Provide a rich experience for on-demand and live linear streaming. Lumen’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).

Content Delivery Network provides a rich experience for streaming on-demand content.

Content Delivery Network enables SSL acceleration and delivery with CDN Services.

SSL Private Certificate

Enable SSL acceleration and delivery with CDN Services, while serving from your own domain (vs. using a CDN-provided wildcard certificate). This approach allows organizations to provide their own certificate (or a third-party certificate) to be published to Cloud CDN delivery points.

Content Delivery Network Use Cases

CDN brings content and customers closer
Closing the Gap Between Users & Content

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.

Delivering streaming online video globally using CDN
Establishing a Global FOOTPRINT® technology for Streaming Online Video

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® technology that could offer excellent performance when faced with large amounts of traffic, as well as responsive customer service.

CDN improves security and reduces latency
Added Security, Protection from Downtime

Lumen’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.

“Everywhere in the world, at all times of the day, customers demand a perfect experience. Deliver on those expectations through fast, secure and reliable access with the Lumen Content Delivery Network."
