What Happened with the CrowdStrike Outage and How Your Business Can Avoid Similar Issues

On Friday, July 19, 2024, many businesses around the world faced a sudden IT outage. It started in Australia and quickly spread across Asia, Europe, and the Americas, hitting the travel industry especially hard. The cause of this massive disruption was traced back to CrowdStrike, a leading cybersecurity company.

What Does CrowdStrike Do?

CrowdStrike is a major player in the cybersecurity world. They help businesses protect their computers and data from hackers and cyber threats. Their main product, called Falcon, uses advanced technology to prevent cyber attacks by monitoring and protecting computers and networks.

What Happened?

The disruption caused computers to crash, showing a blue error screen. Initially, it seemed like a problem with Microsoft Windows. However, the issue was traced back to an update in CrowdStrike’s Falcon product. This update had a flaw that caused many computers to fail and restart repeatedly.

Impact of the Outage

The outage affected about 8.5 million Windows devices globally. Many important services and businesses were disrupted, including airlines, airports, banks, healthcare providers, media outlets, retailers, and more.

CrowdStrike’s Response

CrowdStrike quickly rolled back the problematic update and took steps to prevent such issues in the future. They improved their testing processes and made it easier for customers to manage updates. They are also providing more information and support to help affected businesses recover.

How Can Your Business Avoid Similar Problems?

Here are some simple steps to protect your business from similar IT issues:

1. Test Updates Before Full Deployment: Instead of updating all your systems at once, try the update on a few computers first to see if there are any problems. This way, you can catch issues before they affect your entire business.
2. Have Backup Systems in Place: Make sure you have backup systems that can take over if something goes wrong. This ensures your business can continue operating even if part of your IT system fails.
3. Create a Disaster Recovery Plan: Plan ahead for IT disruptions. Know what steps to take to get your systems back online quickly and ensure your business can keep running smoothly.
4. Keep Track of Your IT Assets: Maintain a list of all your computers, software, and other IT assets. This helps you manage updates and troubleshoot issues more effectively.
5. Educate Your Employees: Make sure your employees know how to recognize and avoid potential threats, such as fake emails or malicious websites. Regular training can help prevent security breaches.

The CrowdStrike outage was a wake-up call for many businesses. By taking these proactive steps, you can better protect your business from similar IT issues and ensure your operations stay up and running.
