Overview

CDNLion was a content delivery network provider founded in 2013, offering services to accelerate websites, images, and video streaming through a network of over 110 data centers worldwide. Based in Prague, Czech Republic, it served customers seeking global content delivery. The company is no longer independently operational and has been integrated into LaunchCDN, which continues to offer CDN services leveraging multiple providers.
Peer5 operated a peer-to-peer (P2P) content delivery network (CDN) specializing in live video streaming, leveraging WebRTC for in-browser, clientless enterprise CDN (eCDN) solutions. Founded in 2012, the company was acquired by Microsoft in August 2021 to enhance video streaming capabilities in Microsoft Teams. Peer5’s technology optimized bandwidth usage through self-balancing mesh networks, serving large-scale enterprise events with up to 2 million concurrent users. As of 2025, Peer5’s standalone services are defunct, with its technology integrated into Microsoft’s eCDN for Teams.

History & Notes

CDNLion was known for its global reach with over 110 data centers and user-friendly APIs, as noted in comparisons with other CDNs like BlazingCDN. Its integration into LaunchCDN reflects the broader consolidation trend in the CDN industry, where smaller providers merge with platforms offering multi-CDN solutions. No conflicting reports of revival or independent operation were found. For further details, see https://www.launchcdn.com.

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.
