UPDATE: At around 3:00pm EST, the Azure team updated the cause for the overheating. A severe weather event, including lightning strikes, occurred near one of the South Central US datacenters. This resulted in a power voltage increase that impacted cooling systems. Automated datacenter procedures to ensure data and hardware integrity went into effect and critical hardware entered a structured power down process.
UPDATE: As of 10:15am EST, the Azure Active Directory and the Azure Bot Service are also now down globally. Additionally…for those trying to check the Azure Status page – good luck. Even the Azure Status page is having problems displaying. Most likely its due to too many requests.
According to the Azure Status page, those in the South Central Azure region, along with Azure Resource Manager (which affects customers globally)…
Engineers have isolated an issue with cooling in one part of the data center, which caused a localized spike in temperature, as the preliminary root-cause. Automated data center procedures to ensure data and hardware integrity went into effect when temperatures hit a specified threshold and critical hardware entered a structured power down process.
Microsoft engineers are working on the problem, but customers assigned to the region are already reporting issues and business operations have halted.
