10-hour Microsoft Azure outage in Europe

Service availability issue in North Europe Summary of impact: From 17:44 on 19 Jun 2018 to 04:30 UTC on 20 Jun 2018 customers using Azure services in North Europe may have experienced connection failures when attempting to access resources hosted in the region. Customers leveraging a subset of Azure services may have experienced residual impact for a sustained period post-mitigation of the underlying issue. We are communicating with these customers directly in their Management Portal. Preliminary root cause: Engineers identified that an underlying temperature issue in one of the datacenters in the region triggered an infrastructure alert, which in turn caused a structured shutdown of a subset of Storage and Network devices in this location to ensure hardware and data integrity. Mitigation: Engineers addressed the temperature issue, and performed a structured recovery of the affected devices and the affected downstream services.
