**Seismic – U.S. East 4 Slowness Incident (4.2 hours)** Customers in the U.S. East 4 region experienced slow page loads, delays generating LiveDocs and workspaces, and API timeouts when publishing content. The issue was caused by an abnormally high volume of automated requests to the Content Manager service, which degraded platform performance. The traffic source was stopped, capacity was added, and performance fully stabilized by approximately 8:30 AM PDT, with a Root Cause Analysis planned to prevent recurrence.
