99.9% Uptime Sounds Great – Until You Do the Math

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:

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?
