## Updates from Klaviyo
### 2026-03-27 04:46 UTC: monitoring
Starting around 8:15 PM US Eastern 26th March, we began seeing delays in real-time segment processing for a subset of customers. Segments may be out of date by up to 2.5 hours.
Engineering have identified a solution and are working to implement the fix shortly. We will continue to provide updates as real-time segmentation functionality is restored.

### 2026-03-27 05:15 UTC: resolved
Real-time segmentation is processing in real-time, and this incident has been resolved.
