3*3*3*3*3*

Article

Uptime is a calculation of the amount of time a server is online, available, and functioning during a given time period. Conversely, downtime is a calculation of the amount of time a server is unavailable during a given time period. Many server operators use third-party uptime monitoring services to improve their uptime performance and to verify targets with their customers.

Calculating downtime

Here's a handy list to gauge how much downtime one may experience over the course of a year, based on a web hosting company's uptime guarantees:

  • 99.9%: 8 hours 46 minutes
  • 99.5%: 43 hours 50 minutes
  • 99.0%: 87 hours 39 minutes
  • 98.0%: 175 hours 19 minutes
