4. postmortem Feb 23, 2026, 05:34 PM UTC

   On February 13, 2026, some customers in us2: Data Center - US West may have experienced intermitted, degraded performance, 500 or 503 errors when accessing their workspaces, or integration failures. Our internal monitoring systems began registering initial, low-level error signals related to this issue at approximately 03:30 UTC. These early signals were below our alert thresholds, but as these signals persisted, our engineers escalated to a formal investigation at 08:54 UTC. **Root cause** The incident stemmed from a transient regional networking condition affecting service-to-service communication within the US2 infrastructure. This degradation caused intermittent timeouts and 503 Service Unavailable responses when services attempted to validate authentication tokens. **Resolution** Our team took immediate action to stabilize the service: * Paused all changes to eliminate potential contributing factors and ensure platform stability. * Isolated and diagnosed the authentication validation pathway to pinpoint the network degradation. * Verified infrastructure integrity by auditing recent maintenance and system updates in our U.S. data center. The affected services recovered as the temporary network issue subsided. Full service was restored at 09:26 UTC. **Corrective and preventative measures** We are committed to learning from this incident and are taking several steps to prevent reoccurrence: * Our engineering teams are conducting a comprehensive investigation to identify the precise trigger to implement targeted safeguards against similar network conditions. * We're deploying improved detection thresholds and correlation logic to identify anomalous patterns earlier, reducing time to investigation for low-level signals. We apologize for any impact this issue may have had on your business operations. We are continuously strengthening our systems and procedures to ensure we avoid future disruptions to your business and users.
