From Azure Support: Starting at approximately 19:34 UTC on 06 Nov 2017 a subset of customers in North Central US may experience degraded performance, network drops, or timeouts when accessing Azure resources hosted in this region. Engineers are also aware of additional alerts for App Service in South Central US. Engineers have determined that this is caused by an underlying network infrastructure Event in this region which is currently under investigation. Impacted services will be listed on the Azure Status Health Dashboard. Engineers continue investigating possible underlying causes, and are working to determine mitigation options. The next update will be provided in 60 minutes, or as events warrant.
