Case Study: CanalChat Grandialogue delivers real-time, scalable chats handling tens of thousands of simultaneous connections with CDNetworks

CanalChat Grandialogue now offers even more interactive chats thanks to CDNetworks

CanalChat Grandialogue, a Paris-based leader in corporate live chat and video services used by roughly 70% of CAC 40 companies, needed to deliver continuously updated content (refreshed every seven seconds) from customers’ premises without overloading on-site bandwidth or degrading the global real-time experience. The company faced the technical and scale challenge of supporting massive simultaneous connections for high‑stakes events and found many CDN providers were too expensive, inflexible, or technologically inadequate.

By partnering with CDNetworks for content acceleration and dedicated technical support, CanalChat had a tailored CDN system deployed in under a week and a single point of contact for ongoing configuration. The solution smoothly handled traffic spikes—supporting tens of thousands of concurrent connections with peaks over 38,000—delivering a reliable, real‑time experience worldwide and giving CanalChat the scalability and peace of mind to serve major corporate and public‑sector clients.
