    We have implemented a fix for errors and feedback ingestion in our EU region, and latency for those pipelines has returned to normal. We are still working on fixing our attachments ingestion pipeline in EU.

    The backlog on attachments in our EU region is fully burned, and latency is back to normal. While new error events are being processed with normal latency, we have a backlog of old error events that we are now burning through.
