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.
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
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.
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.
