A more detailed preliminary root cause and next steps update will be provided within 3 business days of this notification. Additionally, we are continuing to monitor network health as we work through the post incident review process and have added mechanisms to help prevent this particular issue from re-occurring. Next Steps: We are continuing to investigate the underlying cause for this event to help establish the repairs necessary to improve our processes and the platform to help prevent and reduce the significance for this class of issue in the future. We applied configuration changes to deter the increased spike of requests experienced and improve the traffic balancing to reduce load on the network and restore network connectivity to normal in affected regions. Network monitoring detected and alerted upon increased packet drops occurring on the Azure network.

This helped prevent some failures and timeouts, butВ customers still experienced high latencies. Mitigation: Upon detecting increased load, automated throttling was activated at several levels of the Azure stack. As such, infrastructure that handles this request traffic exceeded operational thresholds and caused intermittent packet drops for Azure customer traffic. Preliminary Root Cause:В This issue was the result of a significant increase in request traffic across multiple resource components within the Azure network that support Azure service performance. Summary of Impact: Between as early as 08:00 UTC and 13:20 UTC on 29 July 2022, customers may have experienced intermittent connectivity and/or network related issues when attempting to access or manage Azure resources across multiple regions throughout the duration of this event.
