Despite early reports, the recent major IT outage was not a cyber attack but a combination of failures in CrowdStrike's Falcon sensor platform and parts of Microsoft's Azure cloud infrastructure.
The incident demonstrated the significant impact of technology dependencies, causing global inconvenience, financial losses potentially amounting to billions, and challenges in system recovery and explanation.
The outage resulted from updates in Microsoft's central US region affecting Azure and Microsoft 365 services, alongside a content update by CrowdStrike leading to major issues, highlighting the intricate nature of system interdependencies.
