A AWS foi quebrada e um dia inteiro de trabalho não se encaixa nos critérios para notificar os clientes.
On Tuesday afternoon 21/2/2017 AEDT we discovered an issue that led to increased error rates with ListUsers API calls in Sydney region where empty results were being returned for a limited number of customers. At the time, it was still possible to search for users by specifying Username or user attributes or filters such as Status or Enabled using the same API. Apart from impacted functionality of ListUsers API used for listing existing users, all other service functions were operating as expected.
The issue which was isolated to Sydney region and a limited number of customers only, was resolved soon after being detected and the service has been operating normally since. According to AWS management this issue did not meet the criteria for an announcement in service health dashboard and on behalf of AWS I apologize for any inconvenience this may have caused in your environment.
