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 Level3’s CDN is no longer active, and its network assets are now managed under Lumen Technologies.
Lumen Technologies, formerly CenturyLink, was a telecommunications company that provided content delivery network (CDN) services until October 2023, when it sold select CDN customer contracts to Akamai. The company has since exited the CDN business to focus on enterprise connectivity, fiber infrastructure, and AI-driven network solutions. Its CDN services were used by enterprises and media companies, notably for events like the NFL Wild Card game on Peacock.

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.
Lumen’s CDN operations were part of its broader telecommunications portfolio, leveraging its global fiber network. The decision to sell its CDN contracts to Akamai aligned with a strategic shift toward enterprise fiber, AI infrastructure, and network-as-a-service offerings. The transition was completed smoothly under a 90-day agreement, with no reported service disruptions during the handoff.
