Notebook services are unavailable

Summary:

On 3rd Feb 2026, Aera identified an issue impacting notebook services across multiple environments. Users were unable to load or access notebook functionality. The Production Services Engineering (PSE) teams initiated an immediate investigation and confirmed that the issue was caused by an upstream cloud provider event. Corrective actions were applied at the cloud provider level, after which services began to recover. Aera completed validation checks to confirm full restoration, and all affected environments were confirmed operational.

Customer Impact:

During the outage window, users experienced an inability to access notebook services across multiple environments, impacting workflows that rely on notebook-based analysis and execution.

Root Cause:

The issue was caused by an upstream cloud provider configuration change that disrupted access to storage resources used to support notebook services. This resulted in notebook services failing to load until the configuration was corrected by the cloud provider.

Remediations:

Aera teams promptly investigated the issue and worked closely to monitor recovery while the cloud provider addressed the underlying configuration change. Once the corrective actions were completed, Aera performed validation and sanity checks to ensure notebook services were fully restored and functioning as expected.

Future Mitigating Actions:

Aera is strengthening monitoring and alerting around critical platform dependencies to improve early detection of similar upstream conditions and enable faster response and communication in the future.

We have confirmed internally and with our customers that the Notebook services are now fully restored.
