Akamai has identified the issue and implemented a fix. Normal access and use of Captivate should be restored - we will continue to monitor and update.
Update: This issue is affecting multiple platforms, hosts, and podcast apps/platforms, resulting in playback issues on those apps. We are continuing to work with the 3rd-party team on this.
