On August 5, Microsoft experienced a new outage in the Azure cloud, which affected several services for customers in North and Latin America, writes the BleepingComputer resource. According to the company, the problems began around 18:22 UTC (21:22 Moscow time) and affected services using the Azure Front Door (AFD) cloud CDN service. Microsoft said the incident was caused by a “configuration change.” “We rolled back this change, and since 19:25 UTC (22:25 Moscow time) a recovery has been observed in most services,” the company said.
BleepingComputer noted that customers in the UK were also reporting errors connecting to Azure services (including Azure DevOps), and the Azure DevOps status page noted that users in Brazil were also experiencing issues. Downdetector received thousands of user reports of problems connecting to servers and logging in, although the Service Health Status page indicated no problems with Azure throughout the outage.

Last week, Microsoft experienced a longer outage that was caused by a DDoS attack that targeted several Azure Front Door and CDN sites. “Although the initial trigger event was a DDoS attack that activated our DDoS protection mechanisms, the initial investigation found that an error in our protection implementation increased the impact of the attack rather than mitigating it,” Microsoft said.
