## Timeline of updates

- **resolved** 2023-02-28 14:00 UTC: The latest server release required the event to have anonymousId/userId of string type. This led to gateway rejecting events with non-string type fields mentioned above. Events of above category were not ingested by RudderStack and therefore not sent to downstream cloud mode destinations from 8:30AM TO 2:30PM UTC for all enterprise customers.

_From the vendor’s published history: only the final update text is available for incidents before Rewindex began polling this page._
