    We have identified an issue that may affect the ability to create new CDW Data Sources for customers in profiles with server-side concurrency or CloudStream. At this time, existing CDW Data Sources are not impacted. The risk is limited to the creation of new CDW Data Sources in concurrency or CloudStream enabled profiles only. As a precaution, please do not create any new CDW Data Sources until further notice. Engineers are actively working on a fix and will continue to provide updates as they become available. We apologize for any inconvenience. Please reference status.tealium.com for the latest updates.
