User Event Data Loss
Incident Report for Optimizely.com
Resolved
Due to an internal issue in our Event Ingestion system, we irrecoverably lost a very small fraction of events ingested today between 2.10pm PST and 2.20pm PST. Our engineering team detected and resolved the situation so no data is lost after 2.20pm PST.

The impact of this is that some customers may not see the entire events they sent (via Optimizely X clients or the public Event API users) in that 10-minute period reflected on their Results page or in their Results Exports. It is worth noting that this should not affect the statistical validity of the Results for these experiments.
