On November 14, 2025, between 8:00 AM and 4:54 PM PST, some PlayFab customers experienced delays in Bulk Segmentation features. This resulted in delays in player profile updates, segment exports, and scheduled tasks. The issue was caused by a state in the ADX cluster powering the features, which led to the materialized view becoming unhealthy. We applied manual recovery steps and collaborated with the ADX team to resolve the problem, as the cluster was in a degraded state.

Impact

Root Cause Analysis
