Most hosting companies advertise 99.9% uptime.
That sounds excellent.
Until you do the math.
What 99.9% Uptime Means
99.9% uptime equals:
- 43.8 minutes downtime/month
- 8.76 hours downtime/year
That's almost an entire business day offline every year.
What About 99.95%?
99.95% uptime equals:
- 21.9 minutes/month
- 4.38 hours/year
Better, but still significant.
99.99%
99.99% uptime means:
- 4.38 minutes/month
- 52.6 minutes/year
This is where many professional SaaS companies aim.
Why Detection Speed Matters
Even if downtime is unavoidable, detection speed determines how much damage it causes.
A site monitored every 5 minutes may stay broken for far longer than necessary.
A site monitored every 30 seconds can be fixed much faster.
The Practical Goal
For most startups and agencies:
- 99.95% uptime
- 30-second monitoring
- Instant WhatsApp alerts
provides a strong balance between cost and reliability.
