Overview
Limelight Networks, later rebranded as Edgio, was a content delivery network (CDN) provider founded in 2001, specializing in digital media and software delivery. It offered services for video streaming, web acceleration, and content delivery with a global network. The company ceased operations on January 15, 2025, following a Chapter 11 bankruptcy filing in September 2024, driven by mismanagement, failed acquisitions, and operational challenges.
Universal CDN, founded in 2015 and headquartered in Sofia, Bulgaria, offers a global content delivery network focused on delivering web content, video streaming, and live media. It serves businesses ranging from small startups to large enterprises, particularly those needing video-on-demand and live streaming capabilities. The service emphasizes an API-first approach, enabling developers to integrate and manage CDN services programmatically. Universal CDN supports a variety of use cases, including e-commerce, media, and gaming, with a focus on performance and real-time analytics.
Network & Architecture
—
Universal CDN operates a global network with points of presence (PoPs) across North America, Europe, Asia-Pacific, and Latin America. Specific PoP counts are not publicly disclosed, but the provider claims broad coverage with optimized routing for low latency. It leverages partnerships with major ISPs for peering, enhancing delivery speeds. The service is particularly strong in Europe and North America but has less presence in Africa and the Middle East, which may limit performance in those regions.

Pricing
—
Universal CDN offers a pay-as-you-go (payg) model with no minimum commitments, suitable for variable traffic needs. Pricing starts at approximately $0.05 per GB for standard delivery, with discounts for higher volumes. A free trial is available for testing, and enterprise plans are offered for custom needs. Detailed pricing is available at https://www.ucdn.com/pricing.
Integrations & DevEx
—
Universal CDN provides an API-first design for seamless integration with developer workflows. It supports real-time logs for immediate performance insights but lacks Terraform support or advanced IaC tools. SDKs are available for common programming languages, facilitating integration with CI/CD pipelines. The platform does not offer built-in migration tools but provides documentation for transitioning from other CDNs.
When it fits
—
- Businesses needing video-on-demand or live streaming with HLS/DASH packaging and RTMP ingest for media-heavy applications.
- Developers seeking an API-first CDN with real-time analytics for programmatic control and monitoring.
- Small to medium-sized businesses looking for a pay-as-you-go model with global coverage for web and video content.
When it doesn’t
—
- Organizations requiring advanced security features like WAF, bot mitigation, or rate limiting, which are not offered.
- Companies needing extensive edge compute capabilities or key-value storage for serverless applications.
- Users focused on regions like Africa or the Middle East, where Universal CDN’s network presence is limited.
History & Notes
Limelight was a key player in the CDN market, delivering content for major events like the 2008 Olympics and Obama’s inauguration. Its 2022 acquisition of Edgecast aimed to expand its edge computing and security offerings but led to integration challenges and talent loss. Financial restatements in 2023 and a slowdown in internet traffic growth further strained operations. Some assets, like the Uplynk platform, were acquired by Lynrock Lake LP, while Parler Cloud Technologies purchased Edgecast’s CDN business. No official EOL notice remains publicly available.
