Overview
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.
Viblast was a Bulgaria-based company founded in 2013 that specialized in peer-to-peer (P2P) video streaming solutions, offering Viblast PDN and Viblast Player for live and on-demand video delivery. It served broadcasters, content providers, and CDNs, leveraging WebRTC and HTML5 to enable plugin-free HLS and MPEG-DASH playback. The company aimed to reduce bandwidth costs and improve stream quality for high-concurrency live streams. As of 2023, Viblast is reported as out of business, with no active services or official website available.

History & Notes
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.
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 No evidence of asset sales or successor entities exists, and its website (viblast.com) is no longer active.
