5. 26 de agosto de 2026 a las 17:31 UTCpostmortem

   El martes 25 de agosto, entre aproximadamente 1:50 y 2:00 PM ET, y de nuevo brevemente alrededor de las 2:45 PM ET, algunos usuarios encontraron errores, cargas lentas de página o dificultad para abrir libros en Bookshelf Online. Una perturbación similar ocurrió el miércoles 26 de agosto, entre aproximadamente 12:06 PM y 12:17 PM ET. Algunos usuarios también experimentaron problemas de registro intermitente durante estas ventanas. La causa fue una dependencia interna de servicios que se hizo inestable y dejó de aceptar nuevas solicitudes. Otras partes de la plataforma, incluida la entrega de material de curso a través de integraciones de LMS y comercio electrónico, no se vieron afectadas. Hemos identificado el desencadenante probable para la recurrencia del miércoles, están validando una solución, y han endurecido este componente contra la recurrencia. Estamos monitoreando de cerca a través del resto del período de inicio del término.

4. 4 de septiembre de 2025 a las 20:10 UTCpostmortem

   Bookshelf Online experienced a complete service outage this morning due to processing issues with our Manage API. The incident was triggered when our system encountered difficulties handling a large batch of asset updates. While our platform has successfully processed similar volumes in the past, this particular batch appears to have contained edge cases or problematic assets that degraded our API's processing capability. This degradation cascaded through our system, ultimately rendering Bookshelf completely unavailable to users. Our engineering team quickly identified the contributing factors and implemented emergency mitigation measures, including temporarily blocking the problematic API endpoint. We have conducted an investigation and implemented permanent safeguards, including proper rate limiting for our asset update API and enhanced data validation processes. Our team is also reviewing whether any data reprocessing is needed to ensure complete data integrity. Service is fully operational, and we're implementing measures to prevent similar incidents in the future.

8. 25 de agosto de 2025 a las 22:33 UTCpostmortem

   Today, we experienced intermittent service interruption across VitalSource systems. During this incident, users and API integrations encountered slow performance, error messages, and intermittent access issues. The cause was due to significant request queuing in our core API infrastructure. This request queuing caused latency to some of our critical API endpoints, and this latency was then felt across several of our end-user-facing applications as well as the APIs that power our partner applications.  Our engineering team resolved the request queuing issue by adjusting database configurations and Kubernetes cluster settings. This added additional capacity, and we were able to return to normal operations. All systems are now operating normally. Our engineering team's highest priority is to understand exactly why we saw severe request queuing, and we will continue to monitor performance closely.

1. 19 de agosto de 2025 a las 18:55 UTCresolved

   Between 11:15 and 11:50 am ET on August 19, our Launch service experienced degraded performance due to excessive database load from background job activity, which our teams quickly identified and resolved by isolating the problematic processes.
