Information technology (IT) disasters can occur at any time, causing devastating effects on an organisation’s productivity, reputation, and finances. These disasters may result from various factors, including natural disasters, cyber-attacks, hardware or software failures, human error, and power outages. Therefore, it is essential to be aware of the common causes of IT disasters and how to prepare for them. In this article, we will explore some of the common causes of IT disasters and provide strategies on how to prepare for them.

Common causes of IT disasters

IT disasters can occur due to various reasons, including natural disasters, human error, cyber attacks, and equipment failure. These disasters can cause significant damage to an organisation’s critical data, systems, and operations. Therefore, it is crucial to understand the common causes of IT disasters and take preventive measures to minimise the impact of these disasters.

Natural disasters

Natural disasters are one of the most common causes of IT disasters. These can include events such as floods, hurricanes, earthquakes, and wildfires. Natural disasters can cause widespread damage to IT infrastructure and equipment, leading to significant data loss and downtime. In addition to the physical damage caused by natural disasters, they can also impact power and connectivity, making it difficult to access critical IT resources. Preparation for natural disasters is critical, as the damage caused can be catastrophic without adequate planning and response strategies.

Human error

Human error is one of the most common causes of IT disasters. It can happen due to a variety of reasons, such as lack of training, fatigue, distraction, or carelessness. Accidentally deleting important files, misconfiguring system settings, or failing to properly maintain hardware are examples of human errors that can lead to IT disasters. Organisations can minimize the risk of human error by implementing strict access controls and security policies, conducting regular training and awareness programs for staff, and establishing a culture of accountability and responsibility. Additionally, automation and other technology solutions can help reduce the risk of human error by taking over routine tasks and increasing operational efficiency.

Cyber attacks

Cyber attacks are one of the most significant causes of IT disasters in recent times. Hackers and cybercriminals can breach an organisation’s network, steal confidential data, and disrupt business operations. Cyber attacks can take various forms, such as ransomware, malware, phishing, and denial-of-service (DoS) attacks. In a ransomware attack, hackers encrypt an organisation’s data and demand a ransom in exchange for the decryption key. Malware is malicious software designed to disrupt or damage computer systems. Phishing involves tricking users into divulging sensitive information by posing as a trustworthy entity. A DoS attack aims to overload a network with traffic, making it unavailable to users. Cyber attacks can cause significant damage to an organisation’s reputation, financial position, and customer trust. It is crucial to implement robust cybersecurity measures to prevent cyber attacks and have a disaster recovery plan in place in case of a breach.

Equipment failure

Equipment failure refers to the breakdown or malfunctioning of hardware or software components of IT infrastructure that results in the disruption of normal operations. Equipment failure could be caused by various factors such as power surges, overheating, and physical damage to hardware components. When equipment fails, it can result in a loss of data or complete system failure leading to significant downtime and costly repairs or replacements. For instance, a hard drive failure could result in the loss of critical data, while a server failure could lead to extended downtime that could impact the operations of an entire organisation. Therefore, it is important for organisations to be proactive in preventing equipment failure by investing in high-quality hardware and regularly maintaining and monitoring their IT infrastructure.

Preparing for IT disasters

IT disasters can strike at any time and can lead to significant losses for businesses. It is crucial to be prepared for such events to minimise the impact on operations and ensure business continuity. There are several steps that organisations can take to prepare for IT disasters, including disaster recovery planning, regular data backups, staff training, and cybersecurity measures.

Disaster recovery planning

Disaster recovery planning is the process of developing a plan for responding to IT disasters in order to minimise the impact on business operations. It involves identifying potential risks and vulnerabilities and outlining a set of procedures and strategies for responding to them. The goal of disaster recovery planning is to ensure that critical systems and data can be restored as quickly as possible following an IT disaster, allowing the business to continue operating with minimal disruption. Key elements of a disaster recovery plan include defining recovery objectives, identifying critical systems and data, establishing backup and recovery procedures, and assigning responsibilities for implementing the plan. Regular testing and updating of the plan is also critical to ensure its effectiveness.

Regular data backups

Regular data backups are an essential part of preparing for IT disasters. They involve creating copies of important data and storing them in a separate location. This ensures that in the event of an IT disaster, such as a cyberattack or hardware failure, critical data can be quickly and easily restored. Best practices for regular data backups include automating backup processes, using multiple backup locations and redundancy, and regularly monitoring and testing backups to ensure they are working properly. In addition to helping with disaster recovery, regular data backups also provide a sense of security and peace of mind, knowing that important data is always backed up and available for recovery.

Staff training

Staff training is an essential component of preparing for IT disasters. Employees must be trained on how to respond in the event of an IT disaster, including their roles and responsibilities, and the procedures they need to follow to minimize the impact of the disaster. Training should cover areas such as disaster response, business continuity, and incident management. It’s also important to ensure that employees have access to the resources and tools they need to carry out their roles effectively during a disaster. Regular training sessions should be conducted to keep employees up to date with any changes in the disaster recovery plan or new threats that may arise. By ensuring that staff members are well-prepared and know what to do in the event of an IT disaster, organisations can minimise downtime and reduce the risk of data loss.

Cybersecurity measures

Cybersecurity measures are essential in preparing for IT disasters caused by cyber attacks. Organisations should implement various cybersecurity measures to reduce the risk of such attacks, such as firewalls, antivirus software, intrusion detection systems, and access controls. In addition, organisations should conduct regular vulnerability assessments and penetration testing to identify potential weaknesses and vulnerabilities in their systems and applications. By addressing these vulnerabilities proactively, organisations can reduce the risk of cyber attacks and limit the impact of any successful attacks that occur. It is also important to have an incident response plan in place that outlines the steps to be taken in the event of a cybersecurity incident. This plan should be regularly updated and tested to ensure it remains effective in mitigating the impact of an attack.


In conclusion, IT disasters can cause significant damage to businesses, resulting in financial loss, reputation damage, and even closure. Therefore, it is essential for organisations to be prepared for such events. This includes identifying the common causes of IT disasters such as natural disasters, human error, cyber attacks, and equipment failure, and taking measures to mitigate their impact. Disaster recovery planning, regular data backups, staff training, and cybersecurity measures are critical components of a comprehensive IT disaster preparedness plan. By implementing these measures, organisations can minimise the impact of IT disasters and recover quickly from any disruptions.
