The biggest causes of downtime
To prevent downtime, you need to know where it comes from.
| Cause | Percentage |
|---|---|
| Hardware failure | 40% |
| Software problems | 25% |
| Cybersecurity incidents | 20% |
| Human errors | 10% |
| External factors | 5% |
1. Hardware failure
Hard drives, power supplies, memory - everything wears out. The question is not if hardware fails, but when.
2. Software problems
Bugs, conflicts, failed updates, corrupt files - software is complex and sometimes goes wrong.
3. Cybersecurity incidents
Ransomware, malware, DDoS attacks - security incidents are a growing cause of downtime.

4. Human errors
The classics: pressing the wrong button, disconnecting cables, making configuration errors.
5. External factors
Power outage, internet disruption, fire or water damage - things outside your control.
Proactive maintenance: the key
Most downtime can be prevented with proactive maintenance. Professional IT management ensures that monitoring, updates and preventive maintenance are carried out structurally.
Implement monitoring
Continuous monitoring of servers, network, backups and security
Regular updates
Security patches quickly, feature updates tested
Preventive replacement
Replace hardware before it breaks
Keep documentation up to date
Network overview, passwords, procedures
Monitoring
Don’t wait for something to break. Continuously monitor:
Preventive replacement
Equipment has an economic lifespan. After 5 years, a server may still be technically fine, but the risk of failure increases.
| Equipment | Lifespan |
|---|---|
| Servers/storage | 5-7 years |
| Network equipment | 5-7 years |
| Laptops/desktops | 4-5 years |
| UPS batteries | 3-4 years |
The backup strategy
Backups don’t prevent downtime, but they limit the impact. If your system crashes but you have good backups, you’re offline for hours instead of days.

When downtime happens: minimise impact
Despite all measures, something can still go wrong. Make sure you’re prepared.

DIY vs. outsourcing
Can you do this yourself, or do you outsource it?
| Aspect | DIY |
|---|---|
| IT knowledge needed | Yes, internal |
| 24/7 monitoring | Difficult to achieve |
| Costs | Variable, unpredictable |
| During incidents | Solve yourself |
| Suitable for | Simple environment |
Checklist: are you prepared?
Conclusion
IT downtime can never be completely prevented, but you can drastically reduce the risk and impact. The key is acting proactively: monitoring, maintaining, replacing before it breaks, and being prepared for when things do go wrong.
