Between 8:05 AM and 8:30 AM PDT, customers operating in the EU01 (Europe) region may have experienced intermittent errors (5xx) affecting two primary areas:
Data Ingestion: Errors when attempting to send records via the Ingest API.
Real-Time Personalization: Request failures for personalization and profile lookup services.
The disruption was caused by an service interruption with an upstream provider in our data processing layer within the eu-central-1 region. This prevented our systems from successfully persisting incoming data to our streaming infrastructure and executing real-time lookups during the affected window.
The upstream provider has confirmed the issue is resolved. Our engineering team monitored the recovery, and we have confirmed that all services in the EU01 region have returned to normal operating parameters.
Data Integrity: For data ingestion, records that were rejected with a retryable error code during this window should be resubmitted. Records that have already been successfully ingested following the recovery require no further action.
Personalization: Real-time request success rates have returned to 100%.
We are continuing to monitor the stability of the region.
We apologize for any inconvenience this may have caused to your operations. For further questions, please contact our support team at support@treasure-data.com.
