Service disruption on July 16, 2026

On July 16, 2026, WorkOS experienced significant service disruptions due to elevated latency, timeouts, and HTTP 5xx errors across its User Management API and authentication services. The issue was triggered by an anomalous increase in concurrent session creation, which led to a defect in the code path that exhausted the database connection pool. This defect caused requests to hold one database connection while waiting for a second, leading to connection starvation that degraded service. Despite attempts to mitigate the issue, including increasing service capacity, the core problem was identified as a bug in the transaction library that requested an additional database connection. The situation was resolved by disabling the AuthKit Analytics write, allowing the system to recover quickly. Steps are being taken to address the defect, improve system architecture, and enhance monitoring to prevent similar incidents. These measures aim to ensure that unusual traffic does not lead to broad service degradation and that low-priority tasks do not interfere with critical operations.
