Users may be unable to refresh some Power BI dataflows

Title: Users may be unable to refresh some Power BI dataflows User impact: Users may have been unable to refresh some Power BI dataflows. More info: Affected users saw that their refresh operations remained stuck in an "In Progress" state. This issue impacted a subset of Power BI dataflows (Gen1). Final status: We've completed deploying the fix to the remaining impacted environment, and we've validated with internal monitoring that the issue is resolved. Scope of impact: Users that attempted to refresh some Power BI (Gen1) dataflows may have been impacted. Start time: Sunday, August 2, 2026, at 4:00 AM UTC End time: Sunday, August 9, 2026, at 10:56 PM UTC Root cause: A recent service update designed to improve Power BI service monitoring and observability introduced a regression that was preventing some Gen1 dataflow refresh operations from completing successfully. Next Steps: - We're further reviewing the service update to understand how the regression was introduced, and to understand what prevented it from being detected in our update testing and validation procedures, which will allow us to prevent similar issues in future updates. This is the final update for the event.

Title: Users may be unable to refresh some Power BI dataflows User impact: Users may be unable to refresh some Power BI dataflows. More info: Affected users see that their refresh operations remain stuck in an "In Progress" state. This issue impacts a subset of Power BI dataflows (Gen1). Current status: We applied the fix in approximately half of the affected environment, and our service telemetry monitoring has verified that it's addressing the introduced code regression and remediating the impact. We'll provide an updated timeline for the completion of our fix deployment once it’s available. Scope of impact: Users attempting to refresh some Power BI (Gen1) dataflows may be impacted.

Title: Users may be unable to refresh some Power BI dataflows User impact: Users may be unable to refresh some Power BI dataflows. More info: Affected users see that their refresh operations remain stuck in an "In Progress" state. This issue impacts a subset of Power BI dataflows (Gen1). Current status: We’ve determined that a recent service update designed to improve Power BI service monitoring and observability inadvertently introduced a regression that is preventing some Gen1 dataflow refresh operations from completing successfully. We’ve implemented a fix to mitigate the impact and have received confirmation from a subset of affected users that it successfully restores dataflow refresh operations. We’re continuing to apply the fix across affected environments while monitoring service telemetry to confirm recovery. Scope of impact: Users attempting to refresh some Power BI (Gen1) dataflows may be impacted.
