April 2026: Tableau Performance Degradation
Tableau Cloud experienced a 9.5-hour performance degradation that prevented customers from loading embedded Tableau views within Salesforce Lightning Web components, with users encountering "connection refused" errors along with general slow performance, timeouts, and connectivity issues. The issue was traced to a recent deployment in the US West 2 region that handles SSO/Authentication for embedded views. Engineers resolved the incident by rolling back to a previously stable version, with service recovery observed starting at 09:33 UTC.
