Case Study: CERN achieves global, scalable live streaming for high-profile scientific events with Limelight Networks

Limelight’s Winning Formula Delivers Live Streaming for CERN Events

CERN, the European Organization for Nuclear Research, is a world-leading particle physics laboratory that regularly broadcasts major scientific events and announcements to a global audience. Its challenge is reliably livestreaming high-profile discoveries and talks to thousands (and sometimes tens of thousands) of simultaneous viewers without CDN overload or performance degradation during traffic spikes.

CERN partnered with Limelight Networks for content delivery and service support, using Limelight’s private global CDN and 24/7 engineering assistance to ensure high performance and accessibility. The solution has scaled for major events—during the Higgs boson announcement Limelight supported 50,000 simultaneous livestream viewers and about a million on-demand viewers—while maintaining global reach and dependable service for CERN’s scientific and public communications.
