Every uptime tier, in hours and in money
Uptime calculators stop at minutes. An SLA tier is a downtime budget, and a downtime budget has a price — here is both, for all six tiers people actually write into contracts.
The six tiers side by side
Every uptime calculator on the web converts a percentage into minutes and stops there. They are lead magnets for monitoring products, so the money is not their job.
The money is the half of the question that decides anything. These pages carry the time table and the cost of those hours at five revenue bands, plus the fully-loaded cost of the people pulled into every incident.
| Uptime | Down per year | Per month | Lost per year |
|---|---|---|---|
| 99% | 3.7 days | 7.3 h | $500,000 |
| 99.5% | 1.8 days | 3.7 h | $250,000 |
| 99.9% | 8.8 h | 44 min | $50,000 |
| 99.95% | 4.4 h | 22 min | $25,000 |
| 99.99% | 53 min | 4 min | $5,000 |
| 99.999% | 5 min | 0 min | $500 |
Lost revenue is shown at the middle of the five revenue bands priced on each tier page.
