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.
System73, founded in 2013 and headquartered in Santa Cruz, United States, with a registered entity in Malta, provides a MultiCDN platform focused on optimizing video streaming. Its Edge Intelligence solution uses AI to monitor and route traffic across multiple CDNs, improving Quality of Experience (QoE) and reducing costs. The platform serves content providers, particularly in live and VoD streaming, with a focus on scalability and cost efficiency. System73 has delivered high-profile events like the UEFA Champions League Final, achieving significant cost savings. Customers include OTT providers and broadcasters seeking reliable, high-quality streaming in regions with limited infrastructure.
Network & Architecture
—
System73 operates as a MultiCDN, leveraging a global network of partner CDNs without specifying its own Points of Presence (POPs). Its Edge Intelligence platform uses AI to monitor network conditions and select optimal routes, bypassing congestion. It excels in regions like Latin America, particularly Peru, where traditional CDN infrastructure is sparse. The platform employs peer-to-peer (P2P) technology to create centrally orchestrated content delivery trees, reducing reliance on physical CDN infrastructure. This approach supports scalability for high-traffic events but may face limitations in areas with low P2P adoption or restrictive network policies.

When it fits
—
When it fits
- Ideal for OTT providers and broadcasters needing scalable, high-QoE video streaming, especially for live events like sports.
- Suits customers in regions with limited CDN infrastructure, such as Latin America, due to P2P-enhanced delivery.
- Fits businesses seeking cost-efficient MultiCDN solutions with real-time analytics and API-driven control.
When it doesn’t
- Less suitable for applications requiring WAF, DDoS protection, or image optimization, as these are not documented features.
- May not fit small-scale projects or those needing a free tier, as pricing requires direct contact and no trial is mentioned.
- Not ideal for use cases needing edge compute or advanced caching features like tiered cache or instant purge, which lack public support.

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.
