Resolved - This issue has been resolved, and we have confirmed that experiments are now being delivered to production normally. We apologize for any impact this issue may have had on your service.
Jan 18, 11:45 PST
Update - Issues causing some web experiments in basic snippets to not update have been resolved, but some delays may still be experienced with both web experiments and fullstack datafiles. These delays occur infrequently and should still be no longer than 10-15 minutes on average. We’ll continue updating this page as the issue is being resolved.

Update - We’re currently experiencing intermittent failures with updates to some web experiments. In a small number of cases, changes to web-based experiments may not be delivered to production basic snippets. For fullstack experiments and custom web snippets, in some cases, experiment updates may be delayed 10-15 minutes. We’re investigating these issues now and will update this status page with regular updates until the issue is resolved. If you see any unusual issues in your account, please reach out to support.

Update - We are continuing to investigate this issue.
Jan 15, 18:20 PST
Investigating - In a small number of cases, we’re currently experiencing delays delivering updates to running experiments. Changes to your experiments may in some cases take up to 10-15 minutes to reach your snippet or datafile and up to two hours to be reflected in program management. We’re investigating these issues now and will update this status page once the issue is resolved. If you see any unusual issues in your account, please reach out to support.

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.
