iRacing makes use of a Content Delivery Network (CDN) to make downloads available to members.


To change your CDN preference, follow the steps below.


  1. Log in to the Membersite (members.iracing.com) via a web browser (Google Chrome, Firefox or Edge)
  2. Select My Account from the Account menu
  3. Scroll to the bottom of this page and then choose Limelight or Cloudfront in the drop down next to Choose A Content Delivery Network in the Preferences section
  4. Click Save


The No Preference option will randomly assign you to a CDN at the time of download.  This means that you can download from either CDN whenever you initiate the iRacing updater.
