You’ve seen it on every SaaS website:
“We guarantee 99.9% uptime.”
Sounds awesome, right?
Until you do the math.
⏱️ What Does 99.9% Uptime Actually Mean?
Here’s the reality:
| Uptime % | Max Downtime Allowed |
|---|---|
| 99.9% | 8h 45m per year |
| 99.99% | 52m per year |
| 99.999% | 5m per year |
So even at “three nines”, you’re allowed to be down almost 9 hours a year.
If your product is B2B, financial, or API-based — 9 hours of downtime could mean angry customers, lost revenue, and SLA breaches.
🚨 The Real Question: Are You Measuring It?
Most companies claim SLAs, but…
- don’t track actual uptime precisely
- can’t prove historical performance
- only realize there's a gap when a client asks
If you’re not measuring it and showing it, your “99.9%” is just a number.
🛠️ How I Solved This (Without a Big Infra Stack)
I started using Garmingo Status — a simple but powerful monitoring and status page platform.
It helps me:
- Track uptime with multiple monitor types (HTTP, Ping, etc.)
- Define SLA targets
- Automatically generate monthly PDF reports
- Show public & private status pages
- Log incidents and keep users informed
And yes — there’s a free plan that includes SLA tracking.

🎯 Final Thought
99.9% sounds great in marketing —
But transparency, data, and real reporting are what actually build trust.
If you want to back your uptime promises with real metrics, give Garmingo Status a try.
Have you ever had to deal with SLA tracking or angry uptime questions?
