A server that stops responding. A business application that goes unreachable. A network connection that drops. This kind of incident happens — in businesses of all sizes, with or without an internal IT team, with or without a managed services provider.
The question is not whether it will happen, but what it costs when it does — and whether that cost is acceptable given what you have (or haven’t) put in place to prevent it.
Direct costs: what everyone calculates
The first instinct is to count lost time: 8 employees blocked for 3 hours, at €35/h loaded, that’s €840. Easy to calculate, easy to minimise (“that’s manageable”).
This calculation is incomplete.
Direct costs also include:
Emergency intervention. Outside a managed services contract, emergency troubleshooting is billed between €150 and €300/h. Diagnosis plus system recovery over a day can easily exceed €1,500–€2,500, not counting travel costs.
Emergency hardware replacement. A failed drive replaced within 24h costs two to three times its standard price. A replacement server rented at short notice can run €500–€1,500 for a few days.
Recovery work hours. After an outage, teams must catch up: unprocessed orders, backed-up emails, manual data entry for unsynced records. These extra hours have a real cost.
Indirect costs: what no one calculates
This is where the bill becomes serious.
Lost revenue. For an SMB that handles online orders, manages bookings, or bills by the hour, every hour of downtime is directly lost revenue. For a 10-person firm billing €1,500/day per consultant, one day of blockage represents €15,000 of undelivered production.
Contractual penalties. Some client contracts include delivery or processing SLAs. An incident can trigger penalties, a credit note, or simply a difficult conversation with a demanding client.
Reputational damage. Hard to quantify, but real: a client who tried to reach you during an outage remembers it. Several incidents in a year, and questions about your reliability start to surface.
Data loss. If the outage hits a server without a recent backup, or causes database corruption, the cost of reconstruction can be massive — and sometimes impossible.
What it costs in practice
Industry studies converge on figures that surprise most SMB managers:
| Company size | Average cost per hour of downtime |
|---|---|
| < 10 employees | €1,000 – €3,000 |
| 10 – 50 employees | €3,000 – €15,000 |
| 50 – 250 employees | €15,000 – €50,000 |
These figures include direct and indirect costs, excluding major incidents (ransomware, fire, flood).
And the average duration of an unplanned outage — that is, without proactive monitoring, without on-call coverage, without a documented recovery procedure — is 4 to 8 hours for an SMB without internal IT.
Monitoring changes the equation
The difference between a 30-minute outage and a 6-hour outage rarely comes down to the complexity of the technical problem. It comes down to how quickly someone is alerted.
A properly configured monitoring system detects early warning signs: disk at 85% capacity, abnormally high CPU for 2 hours, web service unresponsive for 3 minutes. The alert fires before users report the issue. The intervention starts before the situation deteriorates.
In managed services, this means in practice:
- Alerts received at any hour, handled by a team that knows your infrastructure
- Response time measured in minutes, not hours
- Documented remediation procedures for common incidents
- Structured escalation when the problem exceeds standard scope
The cost of a managed services contract is measured against what it prevents — not what it costs each month when everything works.
Heavy Mind managed clients
Monitoring is included in all our managed services contracts. Your servers, services, and network equipment are watched continuously. Anomalies are detected and handled before they become outages. You receive a monthly report on your infrastructure’s health.
You’re not a managed client?
Heavy Mind can help you:
- Audit your infrastructure: identify weak points and estimate your exposure to incidents
- Set up proactive monitoring: alerts, dashboards, structured escalation
- Define a managed services contract adapted to your size and constraints — no imposed minimum commitment
