Overview
Cedexis was a MultiCDN platform specializing in real-time traffic steering and performance monitoring, optimizing web and cloud application delivery across multiple CDNs and data centers. Founded in 2009 by Julien Coulon and Marty Kagan, it was acquired by Citrix in 2018 and integrated into its Intelligent Traffic Management (ITM) product. The platform was used by enterprises, including media outlets like L’Equipe, Le Figaro, and Le Monde, to enhance global web performance. Cedexis is now defunct, with its ITM product reaching end-of-life (EOL) in October 2025.
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
Cedexis was known for its Radar, Fusion, Sonar, and OpenMix tools, which provided real-time visibility and programmable traffic management across CDNs and clouds. Its acquisition by Citrix aimed to bolster hybrid and multi-cloud performance but faced challenges, including a notable DDoS attack in May 2017 impacting French media clients. The decision to sunset ITM reflects Citrix’s strategic shift, with no reported plans for a direct successor. NS1 Connect has emerged as a key alternative, leveraging similar DNS-based steering technology.
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.
