Overview

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.
NTT Communications, a subsidiary of Nippon Telegraph and Telephone Corporation, provided a content delivery network (CDN) through its Smart Data Platform, powered by EdgeCast, offering global content delivery for enterprises. The service, launched in 1999, supported various industries with robust network infrastructure until its deprecation in 2025. Following the sale of Edgio’s CDN business, NTT Communications announced the shutdown of its CDN platform, with services ceasing on January 15, 2025. Customers were advised to migrate to Akamai to maintain CDN functionality.

History & Notes

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. For further details, see the official press release: https://www.prnewswire.com/news-releases/lumen-announces-sale-of-select-cdn-customer-contracts-to-akamai-301951303.html[](https://ir.lumen.com/news/news-details/2023/Lumen-announces-sale-of-select-CDN-customer-contracts-to-Akamai/default.aspx)
NTT Communications leveraged its telecom expertise to deliver CDN services, primarily targeting enterprise clients in Asia and globally. The partnership with EdgeCast enabled features like instant purge and real-time logs, but the service’s reliance on Edgio led to its discontinuation after the 2024 asset sale to Akamai. Some customers may still access archived documentation or support through NTT’s sales channels during the transition period.
