Summary of Impact: Between at 23:15 UTC on 06 Jul 2023 and 09:00 UTC on 07 July 2023, customers using Azure Monitor may have experienced issues accessing logs, data gaps, and missed / latent alerts. Preliminary Root Cause: We determined a configuration issue triggered a bug, causing a significant unexpected increase in traffic, causing one of our backend services responsible for processing and storing logs to reach throughput limits. This caused the service's control plane to become unresponsive, leading to services becoming unable to retrieve authentication tokens. The resulting impact spread to multiple regions.Mitigation: We throttled heavy consumers and spun up additional infrastructure to process the incoming load, as well as the backlog of requests.Next Steps: We will follow up in 3 days with a preliminary Post Incident Report (PIR), which'll cover the main root cause and repair items. We'll follow that up 14 days later with a final PIR where we will share a deep dive into the...

As of 07:01 UTC on 31 Jan 2023, customers using Virtual Machines in East US 2 may receive error notifications when performing service management operations - such as create, delete, update, scaling, start, stop - for resources hosted in this region. Only Availability Zone 02 is currently impacted, however Availability Zones 01 and 03 are not impacted. Automatic monitoring alerted us of two partitions of a backend service hosted in East US 2 region becoming unhealthy due to a data process issue. Due to dependencies between services, this manifests in failures when performing service management operations for a subset of Virtual Machines customers with resources in a single Availability Zone. We are working to restore the partitions to a healthy state and will provide an update with our progress in 1 hour, or sooner as events warrant.

As of 07:01 UTC on 31 Jan 2023, customers using Virtual Machines, Databricks, and Azure Database for MySQL- Flexible server in East US 2 may receive error notifications when performing service management operations - such as create, delete, update, scaling, start, stop - for resources hosted in this region. PostgreSQL and MySQL would have also been affected. Workaround: Customers may see Error Code on VMSS operation tracking API is InternalExcecutionError, due to this impact. Customers should still be able to scale out and get the VMs allocated. The failures are mainly in the VM delete and update workflows. Current Status: Automatic monitoring alerted us of two partitions of a backend service hosted in East US 2 region becoming unhealthy due to a data process issue. Due to dependencies between services, this manifests in failures when performing service management operations for a subset of Virtual Machines customers with resources in a single Availability Zone. We are nearing compl...

Between 07:05 UTC and 09:45 UTC on 25 January 2023, customers may have experienced issues with networking connectivity, manifesting as network latency and/or timeouts when attempting to connect to Azure resources in Public Azure regions, as well as other Microsoft services including M365, PowerBI.We've determined the network connectivity issue was occurring with devices across the Microsoft Wide Area Network (WAN). This impacted connectivity between clients on the internet to Azure, as well as connectivity between services in datacenters, as well as ExpressRoute connections. Current Status:We have identified a recent change to WAN as the underlying cause, and have taken steps to roll back this change. Our telemetry shows consistent signs of recovery from 09:45 UTC onwards across multiple regions and services. Most customers should now see full recovery as WAN networking has recovered fully. We are working to monitor and ensure full recovery for services that were impacted.The next u...
