Microsoft Fabric outage history

Users attempting to edit semantic models in Direct Lake mode faced failures when adding a table to an existing model. The error Direct Lake query is missing workspace or artifact identity was reported. The disruption affected Microsoft Fabric across Africa, the Americas, Europe, the Middle East, and Asia Pacific, and was limited to editing workflows rather than a full service outage. The issue began around 6:14 PM UTC and persisted until 8:09 PM UTC, during which time edits could not be completed.

Fabric engineers investigated and implemented mitigation, and all regions returned to normal by 8:09 PM UTC. The incident represents a partial disruption focused on semantic-model editing rather than a broader outage.

Microsoft Fabric and Power BI services in the Americas experienced a regional disruption beginning around 2:00 PM UTC, with users reporting connectivity problems, sign-in issues, and slow performance across multiple locations (including Houston, New York, Toronto, and Pune). The impact persisted through the afternoon and was followed by a restoration, with services returning to normal by 3:34 PM UTC. The issue was most prominent for tenants in the North Central US region, per the service status page.

Users in the UAE North region experienced intermittent interactions with Microsoft Fabric, affecting tenants in that region and related Asia Pacific Power BI and Fabric components. The incident began at 10:34 AM UTC when the status page indicated a regional issue. A follow-up at 11:19 AM UTC noted engineers were investigating and would provide an update soon. By 1:34 PM UTC the affected components were back to normal, and services resumed typical operation.

Impact began at 5:29 PM UTC when Microsoft Fabric entered a degraded state tied to Ontology V2 artifacts used as Data Agent data sources. Users reported errors when configuring or querying Ontology V2-backed data, and many experienced slow or failing data pipelines across regions. The disruptions affected operations in Europe, the United States, and the United Kingdom, with UK South showing notable queue delays and overall pipeline executions slowing down. A workaround exists for Ontology V2 artifacts upgraded from Ontology V1 by reverting to the original V1 artifact; there is no workaround for Ontology V2 artifacts created directly without a prior V1 version.

In the North Europe region, Microsoft Fabric experienced issues creating new Ontology artifacts, hindering workflows that rely on artifact creation. The Europe / Fabric component was listed as degraded, with engineers actively working on a fix and an update ETA provided for end of day. Impact began at Sep 28, 2026 7:09 PM UTC and affected artifact creation in that region for several hours.

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.
