## Infrastructure availability

Depending on your project or business case you have different
availbility requirements. In the IT industry, we usually use the
concept of accepted percentage downtime per year. The follow table
lists the typical availability categories:

| %      | Accepted downtime / year |
| 99     | 87h or 3.65 days         |
| 99.9   | 8.76h                    |
| 99.99  | 0.876h or 52.55 minutes  |
| 99.999 | 5.25 minutes             |
