History & Notes
ChinaCache was a pioneer in China’s CDN market, being the first to secure a nationwide CDN operating permit in 2000. It expanded globally with offices in the US, UK, and Hong Kong, and collaborated with partners like Microsoft and Adobe. Despite its early success, financial difficulties led to its NASDAQ delisting in 2019 and the eventual sale of its international operations to EdgeNext in 2023. Some sources note ChinaCache’s contributions to open-source CDN tools, but its standalone services are no longer active. For further details on the acquisition, see: https://www.businesswire.com/news/home/20230214005037/en/[](https://www.businesswire.com/news/home/20230214005005/en/EdgeNext-Completes-Acquisition-of-ChinaCaches-Overseas-Business-Strengthening-Position-in-the-Global-Cloud-Services-Market)
Peer5 was known for its innovative use of WebRTC to create a decentralized, browser-based P2P CDN, reducing server load and improving video delivery for large audiences. The company powered events for over 1 billion users before its acquisition. No official EOL announcement for standalone services was found, but Peer5’s website now redirects to Microsoft’s eCDN page, indicating full integration. Some third-party sources mention continued support for existing Peer5 customers post-acquisition, but this is unconfirmed as of 2025.
