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.
Level3, originally Level 3 Communications, was a multinational telecommunications and internet service provider that operated a global Tier-1 network and content delivery network (CDN) until its CDN services were discontinued in 2023. Acquired by CenturyLink (now Lumen Technologies) in 2017, it provided core transport, IP, voice, video, and content delivery for medium-to-large internet carriers. The CDN focused on video delivery, large object caching, and edge computing, serving clients across North America, Latin America, Europe, and parts of Asia. Level3’s CDN is no longer active, and its network assets are now managed under Lumen Technologies.
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.

Integrations & DevEx
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.

When it fits
- Businesses needing low-latency video or gaming content delivery with global reach.
- Enterprises seeking integrated DDoS protection and WAF for secure content delivery.
- Developers using Terraform or APIs for automated CDN management.
—
When it doesn’t
- Organizations requiring extensive edge compute or serverless functions, which G-Core lacks.
- Small businesses needing highly competitive pricing compared to BunnyCDN or Cloudflare.
- Users in regions with sparse PoP coverage, where latency may not match larger providers.

History & Notes
—
Level3 was a major player in the CDN market, leveraging its Tier-1 network to deliver high-performance content delivery, particularly for video and large files. Its acquisition of companies like Genuity, WilTel, and TW Telecom expanded its footprint, but the 2017 merger with CenturyLink shifted focus to broader network services. The CDN’s shutdown in 2023 was part of Lumen’s strategic pivot, though specific reasons for discontinuation were not publicly detailed. Some network assets may still support Lumen’s non-CDN services.
