**Issue Summary:** Starting August 20, 2026, users in the UK Production, Pilot, and Stage environments, including Metpol Production and Pilot, experienced disruption affecting Edge Import functionality. **Root Cause:** The issue occurred during a scheduled cleanup activity when the associated cleanup jobs failed across the affected environments. The failed jobs contributed to instability within the supporting services, which impacted Edge Import availability and processing. **Corrective Action:** Cornerstone reviewed the affected service environments and reset the associated capacity to restore service stability. Once the services had recovered, the cleanup jobs were successfully re-run. The affected environments were then monitored to confirm that service health and Edge Import functionality had returned to normal. **Preventive Measures:** To reduce the risk of a similar issue, Cornerstone has taken the following action: * Strengthened post-maintenance validation to confirm service health before and after scheduled cleanup activities.
