## Timeline of updates

- **resolved** 2025-05-27 16:44 UTC: Between 1:08 PM UTC (6:08 AM PT) and 4:25 PM UTC (9:25 AM PT) on Tuesday, May 27, 2025, customers may have experienced issues with their browser SDKs connecting to the Flag Delivery Network's polling services. This time window represents the outer bounds of potential impact; each customer's actual impact may vary depending on the cache expiry of their environment data. Customers who have implemented their own caching mechanisms outside of LaunchDarkly's SDKs may have had additional recovery time. We resolved the issue and impacted services have returned to normal operation.

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