Microsoft has revealed details of an incident where an automated process, designed to trigger when custom keys are removed from KeyVault, caused TDE databases to be dropped from Azure on 29 January 2019. Microsoft tried to restore customer data from a five-minutes-ago snapshot resulting in empty databases and new database names for some. Transactions, product orders, and other updates during that five minute period were lost. Compensation is available to affected customers.
