Overview
G-Core, founded in 2011 and headquartered in Luxembourg, operates a global content delivery network (CDN) with a focus on low-latency delivery for video, gaming, and web content. The company serves a range of customers, including gaming platforms, media providers, and enterprises, leveraging its extensive network to optimize performance. Its CDN is designed to handle dynamic and static content, with additional services like cloud hosting and DDoS protection. G-Core targets businesses needing robust global reach and specialized video/gaming delivery.
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
G-Core operates over 150 points of presence (PoPs) across Tier III/IV data centers globally, with a network capacity exceeding 110 Tbps and over 11,000 peering partners. The network spans regions including North America, EMEA, APAC, LATAM, Africa, India, and the Middle East, with an average latency of 30 ms. It uses intelligent routing and TCP/TLS optimization for performance. The company is particularly strong in gaming and video delivery but may have less coverage in certain emerging markets compared to larger providers like Cloudflare or Akamai.

G-Core supports Terraform for programmatic CDN management, enabling versioning and replication across environments. Its API-first approach includes comprehensive documentation for resource configuration. Real-time logs and customizable log exports (5–60 minute latency) via Logs Uploader enhance observability. Migration tools and plugins simplify transitions from deprecated CDNs like StackPath or Lumen Technologies. SDKs and CI/CD integrations are not extensively documented.
