An uptime of 99%, for example, means that a website 3.65 days a year is not available. Or in other figures 7.20 Hours per month or 1.68 hours per week . The time in which a site is not available is called Downtime.
If the server of a web host fails for a certain time there is a downtime. This is usually caused by power failures or technical malfunction of a server. All sites that are hosted on the affected server are thus not available.
