Overview
Alibaba Cloud CDN, operated by Alibaba Cloud, is a global content delivery network with over 1,200 points of presence (POPs) across more than 70 countries. It specializes in accelerating content delivery for websites, video streaming, and large-scale downloads, particularly in the Asia-Pacific (APAC) region and China. The service supports a range of industries, including e-commerce, gaming, and media, with a strong focus on compliance with China’s regulatory requirements. Customers include enterprises and developers needing low-latency delivery in APAC markets. The platform integrates with other Alibaba Cloud services like Elastic Compute Service (ECS) and Object Storage Service (OSS) for streamlined content hosting.
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.
Network & Architecture
Alibaba Cloud CDN operates over 1,200 POPs globally, with a significant presence in APAC, including China, where it holds a Ministry of Industry and Information Technology (MIIT) license for compliance. The network leverages extensive peering with local ISPs in China to ensure low-latency delivery. It uses tiered caching and origin shield to reduce origin server load. The service is optimized for high-traffic scenarios like e-commerce events (e.g., Singles Day), but its coverage in Africa and Latin America is less extensive compared to North America and EMEA.

Pricing
Alibaba Cloud CDN uses a pay-as-you-go (PAYG) model with pricing based on traffic volume and region. A free trial is available, offering up to 12 months of usage for select services like Elastic Compute Service, which integrates with CDN. Per-GB pricing varies by region, with China typically higher due to regulatory compliance costs. Detailed pricing is available at https://www.alibabacloud.com/product/cdn/pricing.

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.
