Microsoft Fabric outage history

Power BI users in the West Europe E cluster experienced intermittent refresh failures and delays, impacting dashboard refreshes and data delivery for a period of roughly the morning window. The issue was acknowledged by Microsoft Fabric at Sep 23, 2026 10:04 AM UTC as engineers began investigating, with updates indicating a regional impact on the Europe / Power BI component. A small amount of user feedback during this time suggested some observers were affected, but the scope remained regional rather than global.

Power BI customers attempted to load and refresh Excel data sources but encountered failures when connecting to Excel workbooks in the September 2026 Fabric release. This affected both Power BI Desktop and the Power BI Service, with users seeing errors such as DataFormat.Error. The issue surfaced across multiple regions, including Americas, Africa, Europe, the Middle East, and Asia Pacific, and persisted for most of a day and a half. Affected workflows included loading workbook data into reports and dashboards and any refresh operations that depended on Excel-based data sources. The incident began at 4:09 PM UTC and was not fully resolved until 2:09 AM UTC, after regional components returned to an operational state.

North Europe users relying on Microsoft Fabric encountered intermittent issues when using Copilot Service and accessing ML experiments and Models. The Europe / Fabric component transitioned to a degraded state around 10:14 AM UTC, with an update at 10:19 AM UTC clarifying that North Europe customers may experience intermittent issues while interacting with Copilot Service and when accessing ML experiments and Models. Engineers investigated the cause, and the service returned to normal by 11:29 AM UTC, with impact lasting roughly an hour.

Fabric customers in the WABI-US-NORTH-CENTRAL-J-PRIMARY region faced a partial disruption to the Dedicated Capacity migration workflow as a migration service failure prevented completing migration activities for Fabric and Power BI in the Americas. The impact began around Sep 14, 2026 5:39 AM UTC and was resolved by Sep 14, 2026 6:29 AM UTC, lasting about 50 minutes. Engineers were actively investigating with an ETA around Sep 14, 2026 8:00 AM UTC for a fix. There were no user reports during the event, and services returned to normal once the migration tasks could proceed.

Power BI users on Microsoft Fabric began experiencing issues creating new Adobe Analytics connections and re-authenticating existing ones around 6:39 PM UTC. The impact was regional across Americas, Europe, Africa, the Middle East, and Asia Pacific, with users reporting failed connections, slow performance, or sign-in prompts. Some observations included errors like DataSource.Error: This API endpoint has been discontinued.

Microsoft Fabric's status updates indicated engineers were investigating and offered a workaround to create the Adobe Analytics connection through Dataflows Get Data and then use it with the Semantic Model. The root cause was identified and the ETA for a fix was adjusted from end of day 4:19 PM UTC to end of day 9:24 PM UTC. By 12:14 AM UTC all regions—Americas, Europe, Africa, Middle East, and Asia Pacific—had returned to normal. There was a noticeable surge in user reports around 8:00 AM UTC through 10:15 AM UTC, with affected users in France, Germany, the United Kingdom, the Netherlands, and other locations.

Microsoft Fabric experienced a brief degradation affecting users in Germany West Central, with some interactions failing while engineers investigated. The Europe / Fabric component was listed as degraded during the incident, and updates were provided as the team worked toward resolution. The issue began at 12:05 AM UTC and was resolved by 12:54 AM UTC.

Users in the Europe region relying on Microsoft Fabric's scheduled refreshes in the Europe / Fabric component (WABI-NORTH-EUROPE-J-PRIMARY) experienced delays. The disruption began at 6:24 AM UTC and was resolved by 6:59 AM UTC, lasting roughly 35 minutes. Engineers were investigating the issue and provided updates with an ETA of 8:00 AM UTC.

In the Central US region, users attempting to work with newly created Data Agent artifacts after adding a data source faced degraded access. Prompts were disabled and an Operation not found error occurred during interactions, interrupting workflows that rely on these artifacts. Beginning at 1:44 AM UTC, the issue persisted for about three hours and was resolved by 4:44 AM UTC as services returned to normal. Engineers were actively investigating, with the next update scheduled for Sep 3, 2026 4:30 AM UTC. The Americas Fabric component transitioned from a warning state back to normal as the problem was resolved.

In the West Europe region, Microsoft Fabric experienced degraded access to reports and data queries, with reports not refreshing and some pipelines possibly stalling. Creation of Data Agents and Environments was affected, impacting related workflows for a portion of users. The incident began at 7:09 AM UTC and engineers promptly investigated, with updates issued as the situation progressed.

In North Europe, Microsoft Fabric users experienced degraded control plane operations, including pausing and deleting resources, with the Europe / Fabric component marked as degraded. The issue began at 1:34 AM UTC and engineers moved to investigate, issuing updates as work continued. This impacted regional management tasks and could slow workflows that rely on control plane actions.
