Incident Report for Hightouch

Resolved

We identified and resolved an issue affecting event processing. Between 1:13 PM and 3:12 PM ET, customers in us-east-1 experienced delayed event processing across Event Collection, Event Streaming, and Realtime Audiences. During this time, Event Streaming, Realtime Audiences, and Event Collection syncs to S3 may have also delivered duplicate events to downstream destinations.
