Audience Preview Failures

Incident Report for Segment

Resolved

Summary: From 10:20 AM to 3:00 PM PDT on April 27th, a global Databricks Compute outage resulted in failed audience preview queries across external workspaces.
Details: The disruption was caused by an upstream infrastructure failure at Databricks, which prevented some preview queries from executing successfully. This issue was localized to the dashboard preview tool; real-time event delivery and audience activations were not impacted.
Resolution: The underlying compute issue has been resolved by the vendor. We have confirmed that preview functionality is fully restored and operating normally.
