Was Your Business Prepared for the CrowdStrike Incident?
On Friday, 19th July 2024, businesses worldwide woke up to an unprecedented IT crisis. What began as an automated software update quickly spiralled into a global tech meltdown, leaving organizations scrambling and IT teams working around the clock. This wasn't just another minor glitch—it was a stark reminder of how vulnerable our interconnected digital world can be.
The Root Cause
The incident originated from CrowdStrike, a leading cybersecurity firm trusted by thousands of companies globally. In the early hours of Friday morning, CrowdStrike deployed an update to its Falcon sensor product, a widely used endpoint protection solution. However, this update contained a critical flaw that caused Windows PCs to crash, displaying the infamous "Blue Screen of Death".
Starting in Australia and rapidly spreading across Asia, Europe, and the Americas, the issue affected an estimated 8.5 million Windows devices worldwide. The root of the problem lay in a faulty channel file that effectively caused a "boot loop"—a situation where affected machines couldn't complete a stable boot cycle.
The Widespread Impact
The impact was swift and far-reaching. Major airlines like American Airlines, Delta, and Lufthansa faced significant disruptions. Financial institutions, including the London Stock Exchange and Lloyds Bank, grappled with system failures. Even healthcare providers, media businesses, and retailers weren't spared. This seemingly small technical glitch had cascading effects, paralysing critical systems across various industries.
The Road to Recovery
CrowdStrike acted quickly to address the issue, rolling back the problematic update and providing workaround information. However, the process of recovering affected systems has been challenging and time-consuming for many organizations. As of now, while the immediate crisis has been contained, many businesses are still in the process of fully restoring their systems and assessing the impact.
How Can Businesses Prevent This in The Future?
This incident serves as a wake-up call for businesses of all sizes. It highlights the critical importance of having robust disaster recovery and backup solutions in place, but also to not overlook the weaknesses from within - in this case an ill-fated automated update from a hitherto trusted vendor. While it's impossible to prevent every potential issue, one thing organizations can do to significantly mitigate risks and minimise downtime is implement a comprehensive backup and recovery strategy, with a robust software solution that allows for remote recovery and management of devices at scale.
To minimise the impact of similar incidents in the future, businesses need to take proactive steps:
Establish a Comprehensive Disaster Recovery Plan
Every organization, regardless of size, should have a well-thought-out disaster recovery plan in place. This plan should outline clear procedures for responding to various IT disasters, including failures caused by 'friendly' systems like the CrowdStrike incident. If you're unsure where to start, our Disaster Recovery Guide offers practical advice on creating and implementing an effective plan.
Leverage Advanced Recovery Technologies
Implementing the right technologies can significantly reduce downtime and data loss in the event of a system-wide failure. Look for backup and recovery solutions that offer features such as:
- Rapid Image Restore: This functionality allows you to quickly revert affected systems to a known good state, bypassing the need to wait for vendor-specific fixes.
- Centralised Management: Solutions that offer centralised control but allow for localised execution can dramatically speed up recovery times, especially in widespread incidents.
- Scalable Recovery: Opt for systems that don't require an expert at each affected location, allowing for efficient, large-scale recovery efforts.
- Recovery Rehearsal: Choose solutions that allow you to prepare and practise your recovery processes in advance, leveraging virtualized environments to mount your recovery media, ensuring your team is confident and ready when a real crisis hits.
By incorporating these technologies and strategies into your IT infrastructure, you can significantly reduce the impact of incidents like the CrowdStrike update failure, ensuring your business stays up and running even when faced with unexpected challenges. Whether your organization needs a standalone solution, or something scalable, speak to one of our experts who can help you choose the right solution.
What’s next on The Horizon?
As we reflect on incidents like the CrowdStrike update failure and consider how to better protect our data and systems, it's crucial to keep in mind the upcoming NIS2 Directive. This new EU regulation will require many organizations to implement stricter cybersecurity measures, included under the 'Business Continuity' measures required is a robust backup and recovery strategy.
NIS2 aligns closely with the lessons learned from the CrowdStrike incident. It emphasises the need for rapid recovery capabilities, regular testing of backup procedures, and comprehensive incident response plans - all key business continuity elements that prevent and mitigate the impact of large-scale IT failures.
As businesses reassess their processes and systems in the wake of the CrowdStrike incident, there's an opportunity to address current vulnerabilities while also preparing for future regulations. By tackling both issues simultaneously, organizations can strengthen their IT resilience and position themselves well for the upcoming NIS2 compliance requirements.

Looking Ahead
As we move forward, it's clear that resilience and preparedness are key to navigating the complex landscape of modern IT infrastructure. Businesses need to regularly review their backup and disaster recovery strategies, ensuring they have the tools and processes in place to respond effectively to unforeseen incidents.
In an era where a single software update can have global repercussions, being prepared isn't just a best practice—it's a necessity. The CrowdStrike incident serves as a powerful reminder that in the world of IT, a bit of prevention, even from 'friendly fire', goes a long way in avoiding a lot of headaches later on.
