Microsoft blackout happened due to DDoS attacks
A distributed denial of service (DDoS) attack was responsible for the blackout that hit Microsoft 365 and Azure services around the world last Tuesday (30). Microsoft itself confirmed the cybercriminal attack and provided more positioning details.
The company explains that “an unexpected spike in usage resulted in Azure Front Door (AFD) and Azure Content Delivery Network (CDN) components performing below acceptable limits, leading to intermittent errors, timeouts, and latency spikes.
Although the initial trigger event was a distributed denial of service (DDoS) attack, which activated our DDoS protection mechanisms, initial investigations suggest that an error in the implementation of our defenses amplified the impact of the attack rather than mitigating it. ”.
