Impact Statement: Starting at 11:39 UTC on 24 April 2026, a platform issue resulted in provisioning, scaling, and connectivity issues for customers with Azure workloads hosted in the East US region. This issue initially affected one availability zone in East US. As traffic was automatically rerouted and shared services were involved, some customers in other availability zones may have also experienced an impact. Current Status: We detected this issue through our automated monitoring, which identified an unusual increase in failures within the services supporting virtual machine and virtual machine scale set operations in the East US region. We have taken steps to stabilize the affected services and address the underlying issue, while continuing the investigation to determine contributing factors. The next update will be shared within 60 minutes, or as events warrant.
