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 Some sources note ChinaCache’s contributions to open-source CDN tools, but its standalone services are no longer active.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)
Viblast was recognized for its innovative use of WebRTC for P2P video streaming, winning awards like the Streaming Media European Readers’ Choice for Delivery Network in 2014. Its technology was particularly suited for large-scale live streaming, claiming up to 90% bandwidth savings. No official EOL announcement was found, but PitchBook data confirms the company ceased operations by March 2023. No evidence of asset sales or successor entities exists, and its website (viblast.com) is no longer active.
