Overview
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.
Telefónica, a Spanish multinational telecommunications company founded in 1924, operated a content delivery network (CDN) as part of its broader telecom services. The CDN focused on delivering content across Europe and Latin America, leveraging its extensive network infrastructure. It served enterprises, media companies, and telecom partners but ceased CDN operations as part of a strategic pivot away from certain business units. As of 2025, Telefónica’s CDN is defunct, with the company focusing on core telecom, IoT, and AI services.

History & Notes
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.
Telefónica’s CDN leveraged its telecom backbone, offering low-latency delivery in Europe and Latin America. The service supported instant cache purging and API-driven configurations, as noted in historical reports. The decision to sunset the CDN aligns with Telefónica’s broader strategy to exit non-core markets and invest in 5G, IoT, and cloud security. No conflicting reports suggest a revival of the CDN.
