Affected users saw an error reply. Microsoft attributed the outage to a capacity scaling issue and reported an unexpected increase in traffic in its monitoring telemetry. It manually scaled capacity while also identifying a separate load-balancing issue and changing its load-balancing rules. Microsoft later reported that it had resolved the incident by reverting a recent policy change affecting service traffic balancing, and that telemetry confirmed the impact was fully resolved. No AI agent was involved; the record concerns service availability rather than model behaviour.","tags":[],"date_detected":null,"near_miss":null,"root_cause":null,"root_cause_detail":null,"failure_class_detail":null,"responsible_party":null,"adversarial_actor":null,"input_provenance":null,"time_to_contain":null,"operations_paused":null,"remediation":null,"precursor_events":null},"impact":{"direct_loss_usd":null,"remediation_hours":null,"records_exposed":null,"third_parties_affected_count":null,"severity":"moderate","harm_class":[],"affected_description":null,"protected_class_involved":null,"data_categories_exposed":[],"loss_range_usd":null,"reversibility":null,"downstream_exposure_count":null},"evidence":{"sources":[{"url":"https://www.bleepingcomputer.com/news/microsoft/microsoft-investigates-copilot-outage-affecting-users-in-europe/","publisher":"BleepingComputer","date":"2025-12-09","type":"press","title":"Microsoft investigates Copilot outage affecting users in Europe - BleepingComputer","archived_url":null,"attachment":"first_report","independence":"independent"}],"per_field_confidence":{"system.developer":"C","event.incident_class":"D","impact.severity":"D","event.summary":"C","system.autonomy_level":"D","system.deployment_context":"D","event.trigger":"D","event.detection_method":"D","context.country":"D","event.date_disclosed":"D","context.denominator_available":"D"},"field_citations":{"system.developer":[{"source_index":0,"quote":"Microsoft is working to mitigate an ongoing incident that has been blocking users in Europe from accessing the company's AI-powered Copilot digital assistant."}],"event.incident_class":[{"source_index":0,"quote":"Microsoft added that the incident was caused by a capacity scaling issue that is now being addressed."}],"impact.severity":[{"source_index":0,"quote":"According to a service alert (CP1193544) seen by BleepingComputer, the outage may affect users in the United Kingdom or Europe who can't access copilot.cloud.microsoft, m365.cloud.microsoft, Copilot button within the Edge browser, Microsoft Copilot for Microsoft 365 apps."}],"event.summary":[{"source_index":0,"quote":"According to a service alert (CP1193544) seen by BleepingComputer, the outage may affect users in the United Kingdom or Europe who can't access copilot.cloud.microsoft, m365.cloud.microsoft, Copilot button within the Edge browser, Microsoft Copilot for Microsoft 365 apps."},{"source_index":0,"quote":"Microsoft added that the incident was caused by a capacity scaling issue that is now being addressed."},{"source_index":0,"quote":"Indications from service monitoring telemetry suggest an unexpected increase in traffic has resulted in impact."},{"source_index":0,"quote":"We're manually scaling capacity to improve service availability, and we're monitoring this closely to ensure the expected outcome is achieved."},{"source_index":0,"quote":"Microsoft has identified a separate issue behind the Copilot incident that is causing load-balancing problems and further adding to the overall impact."},{"source_index":0,"quote":"Microsoft says it has resolved the incident by reverting a recent policy change that affected service traffic balancing."},{"source_index":0,"quote":"We've successfully reverted the policy change in all affected environments and our telemetry confirms that the impact is fully resolved,"}]},"notes_on_gaps":"The source is a single press article; it gives no exact start date for the outage, so date_occurred is omitted, and the article date (2025-12-09) is not quoted as a sentence so date_disclosed and date_detected are omitted. No duration or time to contain is stated. No model, version, harness, tools, or autonomy details exist because no AI agent was described; system fields are limited to developer and deployment context. Risks and controls are empty because no listed risk or control fits a capacity and load-balancing outage. The remediation (reverting a policy change) adds no control from the closed list, so no remediation record was made. Severity 'moderate' is my judgement: the scope is bounded to users in the United Kingdom or Europe, but no count of affected parties is stated. Country is omitted because the sources say 'United Kingdom or Europe' without a single country. Industry is omitted as not stated. The separate Defender incident (DZ1193516) and the earlier Defender XDR outage are different incidents and were excluded.
