Yesterday, Microsoft had a major outage with a lot of their online services. And today, Microsoft is serving up a reason for that outage:
An unexpected usage spike resulted in Azure Front Door (AFD) and Azure Content Delivery Network (CDN) components performing below acceptable thresholds, leading to intermittent errors, timeout, and latency spikes. While 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.
So Microsoft was hit by a DDoS attack, and their automatic defences amplified it rather than mitigating it. At least they were honest about it and came out with this statement quickly. You can be sure that Microsoft will correct the issues that they found here so that a DDoS attack doesn’t have the same effect as it did yesterday.
