Summary of impact: Between approximately 19:34 UTC and 21:04 UTC on 06 Nov 2017, customers in North Central US may have experienced degraded performance, network drops, or timeouts when accessing Azure resources hosted in this region. Engineers were aware of additional impact for customers using App Service in South Central US. Engineers determined that this was caused by an underlying Network Infrastructure Event in this region which remains under investigation.
Preliminary root cause: Engineers identified configuration change as the potential root cause.
Mitigation: Engineers performed a change to the service configuration to BGP and mitigate the issue.
Next steps: Engineers will continue to investigate to establish the full root cause in approximately 72 hours.
