Global Tech Outage Disrupts Flights, Banks, and Businesses Worldwide: Here’s What Happened

On July 19, 2024, millions of Windows systems crashed, displaying the notorious blue screen of death (BSOD) across multiple different platforms. Technical disruptions brought daily operations to a complete pause for banks, hospitals, airlines, and various other industries. Many individuals faced the dreaded BSOD, rendering their computers unusable. This blue screen caused a standstill in numerous industries, halting operations and productivity. 

According to CrowdStrike, the outage was triggered by a content configuration update that caused Windows systems to crash. "It was not a cyberattack," stated CrowdStrike's Chief Executive, George Kurtz.

Thousands of organizations, including several U.S. government agencies, rely on CrowdStrike’s services, which is why the recent error had such a widespread impact. The disruption locked countless individuals across various industries out of their computers, causing major problems not only for businesses but also for the people who depend on their services. Hospitals and health clinics were forced to reschedule or delay procedures, while travelers faced long waits due to flight delays and cancellations. Although the outage caused the most disruption on Friday, its ripple effects were felt throughout the weekend as IT departments everywhere raced to restore their computer systems.

According to Keatron Evans, a cybersecurity researcher at Infosec, the problem extended beyond individual computers.

The impact of this outage was particularly significant because it affected Windows operating systems, which are used by over 70 percent of servers globally. Some technology experts have raised concerns about Microsoft’s dominant market share, suggesting that it increases the risk of widespread malfunctions like this in the future. 

How long will it take businesses to recover from this outage?

CrowdStrike managed to identify and deploy a fix for the issue within 79 minutes. However, while the fix was implemented quickly, the recovery process for businesses is complex and time-consuming. The problematic update triggered the BSOD on Windows operating systems, rendering them inoperative with the normal boot process.

IT administrators had to manually boot affected systems into Safe Mode or the Windows Recovery Environment to delete the problematic channel file 291 and restore normal operations. This process is labor-intensive, especially for organizations with numerous affected devices. In some cases, physical access to each machine was required, adding further time and effort.

While some businesses managed to apply the fix within a few days, recovery was more challenging for others, particularly those with extensive IT infrastructure and encrypted drives. The use of Microsoft Windows BitLocker encryption technology by some organizations made recovery even more time-consuming, as BitLocker recovery keys were needed.

It is estimated that for some organizations, fully recovering all affected systems could take months.

So, how can your business learn from this situation?

The CrowdStrike Windows outage highlights the significant vulnerabilities associated with our heavy reliance on technology. While system backups and automated processes are essential, having manual procedures in place can greatly enhance business continuity during technical disruptions. 

Perform Disaster Recovery and Business Continuity Planning

Outages can occur for various reasons, making comprehensive disaster recovery and business continuity planning vital. This should include using redundant systems and infrastructure to minimize downtime. By ensuring that critical functions can switch to backup systems as needed, businesses can better handle disruptions and maintain their operations.

Develop and Document Manual Workarounds

Manual workarounds are essential for maintaining critical business processes when technology fails. While common before the digital era, having documented and practiced manual procedures can provide a crucial fallback during outages. This ensures that businesses can continue operating and serving their customers even when technology encounters problems.

Implement Robust Backup and Recovery Systems

Regularly back up critical data and systems and ensure that backups are stored securely and tested frequently. Having a reliable recovery plan in place will help you restore operations quickly in case of a cyber incident.

Conduct Regular Security Training and Awareness Programs

Educate employees about cybersecurity best practices and common threats such as phishing and social engineering. Regular training can help employees recognize and respond to potential threats more effectively.
