Overview
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 Level3’s CDN is no longer active, and its network assets are now managed under Lumen Technologies.
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.
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.

Pricing
—
PageCDN, under SimpleCDN, uses a pay-as-you-go model with plans starting at $5/month. A free tier is not explicitly advertised, but affordable pricing targets SMBs and developers. Specific per-GB pricing is not publicly listed, but the model emphasizes flexibility without long-term commitments. See details at https://www.simplecdn.com/pricing.
Integrations & DevEx
—
PageCDN supports API-first integration, enabling developers to automate content delivery tasks. Real-time logs are available for monitoring performance. It lacks support for Terraform, SDKs, or advanced CI/CD integrations, focusing instead on simple, developer-friendly APIs. Documentation is accessible and covers common use cases for JavaScript, CSS, and font delivery.
When it fits
—
- Small to medium-sized businesses or developers needing a cost-effective CDN for static assets.
- Projects requiring fast integration with open-source libraries like JavaScript and CSS.
- Use cases prioritizing image optimization and HTTP/3 for modern web performance.
When it doesn’t
—
- Enterprises needing advanced security features like WAF, DDoS protection, or bot mitigation.
- Applications requiring robust video streaming (VoD or live) or DRM support.
- Organizations targeting regions with limited POP coverage, such as Africa or Latin America.
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.
