Case Study: iRacing achieves faster, more reliable game downloads with Limelight Networks

Iracing Speeds Up Motorsports Racing Simulation With Limelight Networks Content Delivery Network

iRacing is a global leader in motorsports racing simulation, offering realistic online racing with dozens of cars and tracks. At the start of each 12‑week season members must download large updates (4–5 GB for existing players, up to 30 GB for new users), and inconsistent download performance was harming customer satisfaction and creating a heavy support burden for iRacing’s team. To avoid build-out costs, iRacing sought a CDN with global reach and strong ISP peering to ensure fast, reliable downloads for players everywhere.

iRacing deployed Limelight Origin Storage and Content Delivery, leveraging Limelight’s high cache‑hit rates and private network to reduce hops and bypass internet congestion; implementation with Limelight’s Advanced Service Architects took under a week. Players saw immediate download improvements, support tickets and troubleshooting time dropped dramatically, and customer satisfaction rose—freeing iRacing to focus on enhancing its simulation. Limelight’s 24/7 support and monitoring tools (e.g., cache hit metrics) helped sustain the improved experience.
