We are investigating a networking issue affecting connectivity to Azure services in the West US region. Impacted customers may experience intermittent connectivity failures, increased latency, or difficulty accessing Azure services. Customers with traffic traversing the West US region may also experience downstream impact. We are exploring mitigation options on affected network devices. Early indications suggest the issue is related to network traffic flow through the impacted infrastructure; however our analysis remains ongoing. We are closely monitoring traffic while continuing our investigation. We will provide additional information as it becomes available.
