In 2017, British Airways paid £150 million in compensation after a power outage in one of its IT hubs caused disruption to 75,000 people.
The BA incident is one of the most high-profile examples of how damaging downtime can be. One of the largest airlines in the world can absorb the cost of a downtime event – smaller businesses don’t have that luxury.
Minimising downtime is crucial. In this article, we’ll explain how you can reduce the risk
Downtime Is More Than Major Outages
Downtime refers to any period when a system, network, or service is unavailable or not functioning as intended. While the term often conjures images of massive system failures or catastrophic events, downtime encompasses a wide range of issues, from brief interruptions to prolonged outages.
The most common causes of downtime are:
Cyber Attacks
Cyber attacks are malicious activities aimed at disrupting or damaging systems and stealing data. Ransomware that encrypts data, distributed denial-of-service (DDoS) attacks that overwhelm systems, and phishing attacks that compromise credentials are just some of the methods used to attack businesses.
Impact: These attacks can cause significant downtime, leading to loss of data, financial penalties, and reputational damage.
Hardware Failures
Any malfunctions to computers, servers, and other hardware can cause downtime. Hard drive crashes, power outages, or overheating components are common hardware issues.
Impact: Hardware failures can halt critical applications and services, leading to operational standstills and, in cases involving servers or other storage devices, data loss.
Software Glitches
These are errors or bugs within software applications that cause them to malfunction or crash, including application freezes, compatibility issues, and unexpected bugs introduced during updates.
Impact: Glitches disrupt workflows, reduce productivity, and frustrate users.
System Crashes
More damaging than a glitch, a system crash means the complete failure of an operating system or major application, causing it to stop functioning.
Impact: System crashes usually result in lost work and disrupted operations, and can cause data corruption.
Network Issues
Network issues are Wi-Fi crashes or other problems within the network infrastructure that impede connectivity and communication, like router failures, bandwidth congestion, or configuration errors.
Impact: Network issues can prevent access to critical resources, slow operations, and isolate parts of the business from essential services.
IT Provider-Related Downtime
Everything from software patches to hardware replacements to simple password changes can cause unnecessary downtime if managed incorrectly.
Impact: Downtime caused by a poor IT provider can affect productivity and lead to more serious issues like those listed above.
It’s important to remember that downtime isn’t limited to major outages. There are many issues that can affect business operations. Minimising the occurrence and impact of downtime therefore doesn’t have one solution; each cause requires specific attention and proactive measures to ensure that businesses can operate smoothly and efficiently.

How to Calculate the Cost of Downtime
The most worrying – and damaging – consequence of downtime is financial. If the business is losing productivity, it’s losing opportunities to make money. In the event of a cyber attack or major disaster, immediate losses are compounded by additional costs like fines or rebuilding systems.
A simple calculation for estimating how much money you could lose to downtime is to divide your annual revenue by your annual operating hours.
For instance, a company with £5 million in annual revenue could lose:
- £5 million / 52 weeks = £96,154 weekly revenue (rounded to the nearest pound).
- £96,154 / 40 hours = £2,404 hourly revenue (rounded).
So, that company could lose £2,404 every hour its systems are down. That’s without factoring in lost productivity and lost opportunities.
While company-wide downtime is a relatively rare (but serious) event, minor downtime events that affect single employees or departments are pervasive and all-too-common – and the costs quickly add up. You need effective strategies in place to minimise downtime.
Minimising Downtime Risks
Effective strategies to minimise downtime are essential for maintaining business continuity and efficiency. By implementing proactive measures, businesses can reduce the risk and impact of system interruptions.
Regular Maintenance and Updates
One of the most common downtime causes is issues with software and hardware. By keeping both up-to-date, you can ensure they run smoothly and securely. Regular maintenance prevents potential issues from escalating into significant problems.
Make sure to schedule updates during off-peak hours to minimise disruptions.
Disaster Recovery Planning
Every business should have a robust disaster recovery plan that outlines procedures for responding to downtime events, including cyber attacks, natural disasters, and hardware failures.
The plan includes clear roles and responsibilities, communication protocols, and recovery steps, saving valuable time in a crisis. It’s important that the plan is regularly tested to ensure it is effective and that staff are familiar with their roles during an incident.

Backups
In a data-driven world, businesses need effective, regular backups to protect critical data. Perform regular data backups and store them in multiple locations, including off-site or cloud-based storage, to ensure data can be recovered in case of a primary system failure. Automating backups help ensure consistency and reliability.
Employee Training
Technology is so integral in business today that employees need to use it effectively. Train them on basic IT troubleshooting techniques, such as rebooting systems, checking network connections, and recognising common error messages.
For more serious issues, provide clear guidelines on how to report issues promptly to the IT department.
Cyber Security Awareness
Your staff are the first and final line of defence against cyber attacks. There’s a reason why social engineering techniques through phishing are so popular; it’s easier to trick an employee than a firewall.
Educate employees about cyber security best practices, including recognising phishing attempts, using strong passwords, and securing sensitive data. Reinforce this learning with regular training sessions, such as simulating phishing attacks.
Preventive Measures
Conduct regular system audits to identify vulnerabilities and areas for improvement. This includes reviewing hardware, software, network configurations, and security protocols. Make sure to address any identified issues promptly to reduce the risk of downtime.
