According to Bleeping Computer, a nine-hour global outage in Microsoft services was attributed to a distributed denial of service attack and an implementation flaw in their DDoS Protection services. A Microsoft report on ID KTV1-HWS states that the Azure Front Door (AFD) and Azure Content Delivery Network (CDN) first detected the availability issue. Unfortunately, error in the implementation of the DDoS defenses amplified the impact of the attack rather than mitigating it. Manual remediation proceeded to recover the majority of availability issues within 3 hours, with all global services remediated by 20:48 UTC.
