Overview
PageCDN, rebranded as SimpleCDN in 2025, is a content delivery network that combines public and private content delivery to optimize web performance. It serves developers and businesses seeking to accelerate website loading times, particularly for open-source JavaScript, CSS, and font libraries. The service emphasizes easy integration and affordability, targeting small to medium-sized businesses and individual developers. Its network supports global content delivery with a focus on performance enhancements like image optimization and HTTP/3 support.
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.
Network & Architecture
PageCDN operates a global network with an expanded set of edge locations, though specific POP counts are not publicly detailed. The service leverages a hybrid approach, combining public and private CDN capabilities to reduce latency and improve performance. It has a strong presence in North America, Europe, and Asia-Pacific, with less emphasis on regions like Africa or Latin America. Routing and peering details are not extensively documented, but the service prioritizes developer-centric use cases with straightforward integration.
