Two Nines: 3.7 Days
99% allows over three and a half days of downtime a year. For a business, that is a bad quarter hiding in a good-looking number.
Free Tool · Uptime & SLA Calculator
99.9% uptime sounds great. It’s 8.8 hours down
Uptime percentages are designed to sound flawless, and the decimal points hide entire workdays. Translate any SLA into real hours, translate your actual outages into a score, and see whether the promises and the reality deserve each other.

Decode the Nines
What the percentages actually promise
Each extra nine sounds like a rounding error. In hours, the differences are enormous.
Three Nines: 8.8 Hours
The classic promise: 8h 45m a year, about one lost workday. Fine for some systems, painful for others.
Four Nines: 53 Minutes
Under an hour a year. This is where redundancy, monitoring and real engineering start earning their keep.
When It Fails Matters
8 hours spread over a year is invisible. 8 hours on invoicing day is a crisis. Averages hide the timing.
SLA vs Reality
An SLA is a refund policy, not a force field. Credits for missed uptime rarely approach what downtime cost you.
Your Own Number
Flip the calculator: your outage hours become your real uptime score, ready to compare against what you are paying for.
Earning the Nines
How real uptime is actually built
Nines are not bought with promises. They are built with unglamorous engineering, layer by layer.
Monitoring that never sleeps
Failures announce themselves early to anyone watching. Monitoring converts outages into maintenance tickets.
Maintenance before failure
Patched, healthy, watched systems simply break less. Boring is the strategy.
Redundancy where it counts
Backup internet, failover for critical systems, spare capacity: engineered so one failure is a non-event.
Recovery that is rehearsed
When something does break, a tested recovery plan turns a day of downtime into an hour.
Response that is immediate
Every outage has a clock. A team that answers now, remote and onsite, shrinks every incident.
Honest measurement
You cannot improve what you do not track. We measure your real availability, so decisions run on data.

Questions
Uptime and SLAs, answered
What is an SLA exactly?
A service level agreement: the uptime a provider commits to, plus the compensation, usually service credits, if they miss it. It defines the refund, not the reliability.
Is 99.9% uptime good?
It depends what rides on the system. 8.8 hours a year is fine for a marketing site and rough for the server your whole team works on. Match the nines to the cost of an hour down, our downtime calculator next door gives you that number.
How many nines does my business need?
Start with what an hour of downtime costs you and when outages hurt most. Most small businesses land between three and four nines for core systems, with the critical pieces engineered higher. We help you set the target honestly.
Do SLA credits actually compensate for downtime?
Rarely. Credits are typically a slice of your monthly fee, while your losses are wages, sales and reputation. The real value of an SLA is the incentive it creates, not the refund.
How do I measure my own uptime?
Roughly: add up your outage hours and use the reverse calculator above. Properly: monitoring that records availability continuously, which is part of what we deploy for clients.
Can a small business really get high uptime?
Yes. Four-nines behavior comes from affordable pieces: proactive monitoring, healthy maintained equipment, backup internet and a rehearsed recovery plan. It is engineering, not enterprise budgets.
Do you guarantee uptime?
We commit to response times and build the redundancy and recovery that make outages rare and short, and we measure results openly. Anyone promising zero downtime is selling something else.
