Secret Server Cloud: US - Intermittent Application errors

Incident Overview 

On April 24, 2026, a subset of Secret Server Cloud customers in the US region experienced intermittent errors or connectivity issues when accessing their tenants. The disruption was caused by an outage in our cloud infrastructure provider at the East US data center. The issue originated in a single part of the data center but spread to additional areas as traffic was automatically redistributed, extending the scope and duration of the incident. Full-service recovery was confirmed at 00:15 UTC on April 25, 2026. 

Root Cause 

The outage impacted internal networking components that our platform depends on, disrupting connectivity across the environment. These failures contributed to the intermittent HTTP 500 errors experienced by some Delinea customers during the incident window. The issue originated in one of the Availability zones in East US data center and expanded to other zones as traffic was automatically redistributed, broadening the impact. Our team responded promptly, identifying the root cause at our cloud infrastructure provider and redistributing traffic to other zones. As a precautionary measure, our team initiated a failover to a secondary region, but later determined it was no longer needed and safely rolled back with no additional impact. Service was fully restored after our infrastructure team redirected traffic away from the affected nodes within the primary environment, with full recovery confirmed at approximately 00:15 UTC on April 25, 2026.  

Preventive Actions 

• Evaluate multi-availability-zone node pool configurations to improve platform resilience and reduce the impact of localized data center failures. 

• Establish clear thresholds and decision criteria for triggering regional failover versus in-region mitigation to improve response speed during incidents.
