+ On October 20, 2025, at 06:50 UTC, multiple Salesforce clouds, including Marketing Cloud Account Engagement, experienced a widespread service disruption caused by a Domain Name System (DNS) issue at a third-party cloud infrastructure vendor. Customers experienced delays and failures in background tasks due to data service connectivity issues. Marketing Cloud Account Engagement services were fully restored, and the issue was resolved at 09:30 UTC. The vendor implemented a fix forward, and we closely monitored recovery, scaling resources where needed to stabilize performance.  We apologize for how you and your business may have been affected by this incident. Salesforce is fully committed to minimizing downtime when incidents do occur. We also continually assess and improve our tools, processes, and architecture to provide you with the best service possible.
