Everything You Need to Know About the Global Crowdstrike and Microsoft Outage

On July 19, 2024, a global outage hit several industries and sectors worldwide, causing significant disruptions in the operations of many companies.

The outage was traced back to a faulty update from the cybersecurity company Crowdstrike, which affected Microsoft Windows hosts. This incident highlights the interconnected nature of modern technology systems and the potential consequences of even minor errors in software updates.

Crowdstrike, a prominent cybersecurity firm, released a routine software update that was intended to enhance the security of Windows systems. However, a defect in this update led to widespread disruptions across various sectors. The affected systems included those of major airlines, airports, banks, media outlets, and other companies. The outage caused a ripple effect, leading to flight cancellations, delays, and difficulties in accessing banking services, among other issues.

This IT outage is a stark reminder of how dependent we are on technology and many other things that happen behind the scenes that most of us are unaware of.
