How To Avoid an IT Crisis: Lessons from the CrowdStrike Outage
In July 2024, a software update gone wrong left millions of Windows devices across various industries—including airlines, hospitals, and banks—crippled by the dreaded “Blue Screen of Death” (BSOD). While this was not the result of a cyberattack, the impact was still profound, disrupting essential services worldwide. This incident serves as a powerful reminder for business owners and IT managers of the critical need for thorough software testing, reliable IT management, and robust disaster recovery plans.
In this expanded article, we’ll take a deeper dive into what caused the CrowdStrike outage and discuss concrete steps your business can take to prevent similar crises in the future.
What Exactly Happened During the CrowdStrike Outage?
On July 19, 2024, an update from CrowdStrike—a leader in cybersecurity—triggered widespread system crashes, affecting over 8.5 million Windows devices. The update was meant to enhance the performance of CrowdStrike’s Falcon platform, an endpoint detection and response (EDR) tool, but a flaw in the update caused significant problems.
The issue stemmed from a fault in CrowdStrike’s content validation process. The testing tool failed to detect a critical flaw, which resulted in system crashes, forcing Windows devices into endless reboot loops, and leaving users staring at the notorious BSOD.
Affected industries included:
- Airlines: Flights were grounded, and thousands of travelers were left stranded.
- Healthcare: Hospitals faced delays in surgeries and procedures as electronic health record systems went offline.
- Banking: Several major banks reported outages, leaving customers unable to access their accounts.
This incident, labeled the largest IT outage in recent history, reportedly caused financial losses upward of $5.4 billion for Fortune 500 companies. While CrowdStrike quickly corrected the update, the damage was already done.
The Importance of IT Crisis Preparedness
This event is a sobering example of how interconnected our digital infrastructure has become. With so many aspects of business and daily life dependent on technology, even a seemingly routine software update can have far-reaching consequences if it goes wrong.
But this isn’t just a problem for global enterprises like CrowdStrike. Whether your business has 10 employees or 10,000, the lessons from this outage are clear: Every organization needs to prioritize reliable IT management, rigorous software testing, and a proactive disaster recovery strategy.
Steps You Can Take to Avoid IT Crises
Now that we’ve seen how a single flaw can cause widespread disruption, let’s explore practical steps you can take to safeguard your business.
1. Partner with Experienced IT Professionals
Having a knowledgeable IT team managing your network is the first line of defense against potential issues. Accidents can happen even in the most advanced organizations, but an experienced IT team can help reduce the risk by ensuring that:
- Software updates are thoroughly tested before deployment.
- Regular backups are performed to safeguard your critical data.
- Systems are monitored around the clock for signs of trouble.
Your IT professionals should act as trusted advisors, staying on top of trends, updates, and best practices to keep your business running smoothly.
2. Prioritize Rigorous Software Testing
Before deploying any software update, rigorous testing is crucial. CrowdStrike’s incident was a stark reminder of what happens when software testing falls short. A gap in their testing process allowed the update to proceed, leading to catastrophic consequences.
Your business can avoid similar issues by working with IT experts who have a robust testing protocol in place. This process should include:
- Test environments: Simulating different scenarios to identify potential flaws before updates reach your live environment.
- Quality assurance checks: Ensuring that updates are compatible with your hardware and software configurations.
- Rollback procedures: If something goes wrong, your IT team should have a clear process for reverting to a previous stable version of the software.
Comprehensive testing not only helps prevent problems but also gives your business confidence that new software and updates will function properly in your specific environment.
3. Develop a Robust Disaster Recovery Plan
While proper IT management and testing significantly reduce risks, it’s still essential to have a backup plan. Every organization should have a disaster recovery plan (DRP) in place to ensure business continuity in the event of an IT crisis.
A DRP involves strategies for quickly restoring systems, applications, and data to minimize downtime. The key elements of an effective disaster recovery plan include:
- Data backups: Regular, automated backups of critical business data. These backups should be stored offsite or in the cloud, ensuring you can quickly access them during a crisis.
- Failover systems: Having secondary systems or servers ready to take over if primary systems fail.
- Incident response plan: Detailed protocols that specify who is responsible for what in the event of an outage. This ensures a coordinated and rapid response.
- Communication strategy: Ensuring employees, clients, and key stakeholders are kept informed throughout the recovery process.
4. Conduct Regular IT Audits
Routine IT audits are an excellent way to assess your current systems and identify any potential vulnerabilities. Audits allow your IT team to:
- Identify outdated software and hardware that could pose security or performance risks.
- Review backup and disaster recovery procedures to ensure they’re current and effective.
- Ensure compliance with relevant cybersecurity and data privacy regulations.
IT audits provide valuable insights into your overall network health and ensure that your systems are running optimally.
5. Invest in Cybersecurity Training for Your Team
Even the best technology can’t protect your business if your employees aren’t trained to use it correctly. Many IT issues arise not because of software failures but because employees accidentally trigger them through improper use of systems.
To avoid this, invest in regular cybersecurity training that covers topics such as:
- Recognizing phishing scams and other online threats.
- Safe practices for handling sensitive data.
- Proper protocols for updating and maintaining software.
When your team understands best practices, they become a valuable asset in maintaining your business’s IT security.
Case Studies: How Businesses Can Benefit from IT Crisis Preparedness
Let’s look at a couple of examples of businesses that successfully avoided large-scale IT crises by being proactive:
Case Study 1: A Mid-Sized Law Firm’s Experience
A mid-sized law firm was heavily reliant on its IT infrastructure for managing sensitive client data, contracts, and communications. After conducting a free network assessment, the firm’s IT provider identified outdated systems that were vulnerable to malware and ransomware attacks.
The firm implemented a robust backup strategy, rigorous software testing protocols, and a disaster recovery plan. These steps allowed the business to quickly restore operations after an unrelated system failure, avoiding significant downtime.
Case Study 2: A Regional Retail Chain's Proactive Disaster Recovery
A regional retail chain recognized the importance of having a disaster recovery plan after seeing several competitors suffer prolonged downtime during a ransomware attack. The chain worked with its IT team to build a failover system and implemented automated backups.
When the chain’s primary server went offline due to a software issue, the failover system activated within minutes, allowing the business to continue operations without disruption. The proactive measures saved the chain thousands of dollars in lost revenue and avoided negative customer experiences.
