Summary: On 20th May 2026, Aera identified a platform availability issue impacting multiple East US CDEV (non-production) environments through automated monitoring. The Production Services Engineering (PSE) team promptly initiated an investigation. The issue was identified as instability within the underlying third-party hosted infrastructure, which impacted a subset of services across the affected environments. Remedial actions were undertaken to stabilise the environment, following which services were successfully restored. Subsequent validation checks confirmed that all impacted environments had been restored to full operation. Customer Impact: During the outage window, users experienced intermittent unavailability while accessing the affected East US CDEV environments. Root Cause: The issue was caused by instability within the underlying infrastructure hosted on a third-party cloud provider in the East US region. This instability resulted in service degradation and impacted availability across the affected CDEV environments. Aera’s engineering team worked directly with the affected infrastructure components to restore stability. Remediations: Aera’s engineering teams investigated the infrastructure instability and applied corrective measures to the affected components hosted within the third-party cloud environment. Once stability was restored, services recovered successfully across all impacted East US CDEV environments. Validation and monitoring checks were carried out to confirm full recovery and normal platform operations. Future Mitigating Actions: We are continuing to enhance our monitoring and alerting capabilities to proactively identify similar infrastructure conditions earlier, enabling faster remediation and reducing customer impact.
