Summary of Impact: Between and UTC on 07 Feb first occurrence , customers attempting to view their resources through the Azure Portal may have experienced latency and delays. Subsequently, impact was experienced between and UTC on 08 Feb second occurrence , the issue re-occurred with impact experienced in customer locations across Europe leveraging Azure services. Preliminary Root Cause: External reports alerted us to higher-than-expected latency and delays in the Azure Portal. After further investigation, we determined that an issue impacting the Azure Resource Manager ARM service resulted in downstream impact for various Azure services.

Estimated completion: February Our ARM team will leverage Azure Azure status Door to dynamically distribute traffic for protection against retry storm or similar events.

The Hybrid Connection Debug utility is provided to perform captures and troubleshooting of issues with the Hybrid Connection Manager. This utility acts as a mini-Hybrid Connection Manager and must be used instead of the existing Hybrid Connection Manager you have installed on your client. If you have production environments that use Hybrid Connections, you should create a new Hybrid Connection that only gets served by this utility and repro your issue with the new Hybrid Connection. The tool can be downloaded here: Hybrid Connection Debug Utility. Typically, for any troubleshooting of Hybrid Connections issues, Listener should be the only mode that is necessary. Setup a Hybrid Connection in the Azure Portal as per usual, e. By default, this listener will forward traffic to the endpoint that is configured on the Hybrid Connection itself set when creating it through App Service Hybrid Connections UI.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Azure status provides you with a global view of the health of Azure services and regions. With Azure status, you can get information on service availability. Azure status is available to everyone to view all services that report their service health, as well as incidents with wide-ranging impact. If you're a current Azure user, however, we strongly encourage you to use the personalized experience in Azure Service Health.

Estimated completion: February Our ARM team will audit dependencies in role startup logic to de-risk scenarios like this one. From June 1, , this includes RCAs for broad issues as described in our documentation. Completed Our Key Vault team has fixed the code that resulted in applications crashing when they were unable to refresh their RBAC caches. How are we making incidents like this less likely or less impactful? Automated communications to a subset of impacted customers began shortly thereafter and, as impact to additional regions became better understood, we decided to communicate publicly via the Azure Status page. However, upon further investigation, we identified a potential network issue with the Azure Resource Manager service which caused impact to additional Azure services including the Azure Portal, Azure Data Factory, Azure Synapse Analytics and Databricks. Completed Our Key Vault team has fixed the code that resulted in applications crashing when they were unable to refresh their RBAC caches. The vast majority of downstream Azure services recovered shortly thereafter. Specific to Key Vault, we identified a latent bug which resulted in application crashes when latency to ARM from the Key Vault data plane was persistently high. While impact for the first occurrence was focused on West Europe, the second occurrence was reported across European regions including West Europe.

Completed We have offboarded all tenants from the CAE private preview, as a precaution. Estimated completion: February Our ARM team will audit dependencies in role startup logic to de-risk scenarios like this one. What went wrong and why? On 21 January , an internal maintenance process made a configuration change to an internal tenant which was enrolled in this preview. How are we making incidents like this less likely or less impactful? This feature is to support continuous access evaluation for ARM, and was only enabled for a small set of tenants and private preview customers. Unbeknownst to us, this preview feature of the ARM CAE implementation contained a latent code defect that caused issues when authentication to Entra failed. This feature is to support continuous access evaluation for ARM, and was only enabled for a small set of tenants and private preview customers. Eventually this led to an overwhelming of the remaining ARM nodes, which created a negative feedback loop increased load resulted in increased timeouts, leading to increased retries and a corresponding further increase in load and led to a rapid drop in availability.
