Microsoft Copilot Outage Disrupts UK and Europe as Manual Capacity Boost Begins

Microsoft says a traffic surge overwhelmed autoscaling prompting manual capacity increases.

Overview

  • A Microsoft service alert labeled CP1193544 flags potential impact for any Copilot user in the United Kingdom or Europe.
  • Users who can access Copilot may encounter degraded functionality in specific features.
  • Service telemetry indicates an unexpected spike in traffic, and engineers are monitoring for improvements as capacity is added.
  • A separate incident, DZ1193516, is causing errors for some admins using Microsoft Defender for Endpoint features such as device inventory and threat analytics.
  • Microsoft has not disclosed how many users are affected, and a Defender XDR portal outage was mitigated about a week earlier.
