Summary AI Generated
A feature disruption on Salesforce Marketing Cloud Engagement Stack 401 prevented end users from logging in across 15 affected database components for approximately 1.8 hours. The root cause was a high volume of login requests from a small number of integrations, which caused timeout errors on login token requests and overwhelmed caching and database services. Salesforce resolved the issue by identifying the problematic integrations and applying rate limits to their requests, confirming no underlying database damage had occurred.
