Summary AI Generated
PostHog EU experienced event ingestion processing delays caused by a problematic migration, preventing events from appearing in the product and queries in a timely manner. The issue was identified and mitigated within approximately 1.5 hours, though users may have seen duplicate events during recovery. Full recovery took an estimated 2 additional hours after mitigation, with no data loss occurring during the incident.
Our estimates for full recovery in both environments are ~2 hours.
