Microsoft has provided an update regarding the Azure Portal outage, revealing that the preliminary cause was a sudden increase in web traffic, which they referred to as a “spike.”
According to Microsoft’s update on the Azure status page, they identified a surge in network traffic that impacted the traffic management of these sites, resulting in customer access issues. In response, Microsoft implemented various measures such as load balancing processes and auto-recovery operations to mitigate the issue. They are actively monitoring the platform’s health.
Microsoft is expected to release a preliminary post-incident review with more information about the Azure Portal incident by the end of the day.
Although Microsoft did not provide specific details about the cause of the connectivity issues, a threat actor known as Anonymous Sudan claimed responsibility for a distributed denial-of-service (DDoS) attack that coincided with the spike in network traffic observed by Microsoft. Anonymous Sudan has previously targeted U.S. companies as a form of protest, possibly related to Sudanese internal affairs. However, there are suspicions that the actual threat actor behind these attacks may have connections to Russia.
When asked to comment on Anonymous Sudan’s claims, Microsoft stated that they are aware of the situation and are conducting an investigation. They assured that necessary steps are being taken to protect customers and maintain service stability.
