Overview
Kingsoft Cloud, founded in 2012, is a leading cloud service provider in China, offering CDN, cloud storage, and computing services. It serves industries like gaming, video streaming, healthcare, and finance, with a strong focus on AI-driven solutions. The company operates as a subsidiary of Kingsoft Corporation and is listed on NASDAQ (KC) and HKEX (3896). Its customers include enterprises leveraging its infrastructure for high-performance computing and AI applications, particularly within the Xiaomi and Kingsoft ecosystems. As of 2025, it reports significant growth in AI cloud revenue and operates data centers globally.
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
Kingsoft Cloud operates data centers in mainland China, Hong Kong, Russia, Southeast Asia, and North America. Specific POP (Point of Presence) counts are not publicly disclosed, but the provider emphasizes a global footprint with strong coverage in APAC, particularly China. Its infrastructure supports high-performance computing for AI and gaming, with robust peering for low-latency delivery in the region. Limitations may include less extensive coverage in EMEA and LATAM compared to providers like Akamai or Cloudflare. The service is optimized for China’s regulatory environment, holding necessary licenses for operation.

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.
