On the 19th, Microsoft Windows system and some of the company's other applications and services experienced large-scale outages, causing many countries' aviation, railways, shipping, finance, medical, hotel and other industries to be unable to operate normally, and the work and life of many companies and individual users were seriously disrupted.

Microsoft CEO Satya Nadella posted on social media X that day to confirm that a software update released by CrowdStrike, a security technology company that provides services to Microsoft, was the main cause of the global outage.

The scope and severity of this outage are extremely rare, and it has sounded the alarm for governments, industries and individual users. Junaid Ali, a cybersecurity expert at the Institution of Engineering and Technology in the UK, pointed out that the scale of this outage may be "unprecedented", posing a major challenge to the global information technology (IT) industry team, but also providing important experience for software engineering professionals.
