iRacing Speeds up Motorsports Racing Simulation with Limelight Networks Content Delivery Network


TEMPE, Ariz.--(BUSINESS WIRE)-- Limelight Networks, Inc. (Nasdaq: LLNW), a leading provider of edge cloud services, today announced that iRacing, the world’s premier motorsports racing simulation company, is using its Content Delivery Network (CDN) to accelerate large software updates delivered worldwide.

At the beginning of each 12-week racing season, members update their software for the latest track and car information. Software updates range from 4-5GB for existing players and up to 30GB for new members, and customers had complained of inconsistent download performance. iRacing implemented Limelight’s CDN to improve performance and ensure all quarterly updates run smoothly. In addition, Limelight’s peering relationships with major global Internet service providers (ISPs) ensure that regardless of where players are located or how they connect to the internet, they have the fastest download possible.

“We’re not set up to build out our global infrastructure to make our downloads available to every location on the planet,” said Nick Bailey, Senior DevOps Engineer at iRacing. “We chose to partner with Limelight to do that so we can focus on making the auto racing simulations as detailed as possible and ensure our members can experience them in a timely fashion.”

Limelight’s high cache hit ratio ensures players can quickly download game files from local points-of-presence, rather than accessing them from distant locations. In addition, iRacing is using Limelight Origin Storage, which allows game files to be accessed and delivered quickly, even if they aren’t already in cache. These capabilities together with Limelight’s high data throughput rates, extensive peering relationships and private global network, lead to faster download speeds for iRacing’s software updates.

“No one wants slow performance or to wait around for slow downloads, especially on a car racing simulator,” said Steve Miller-Jones, Vice President of Product Strategy at Limelight. “Limelight’s private global network makes it possible for iRacing to significantly accelerate extremely large downloads, as well as global game play for all its members.”
