What does 99.99% uptime mean?

Updated Hostnali team

Short answer

99.99% uptime means your website is online 99.99% of the time: at most about 4 minutes and 23 seconds of downtime a month, or about 53 minutes a year. Hostnali guarantees 99.99% uptime on its hosting.

Uptime in minutes

UptimeDowntime per monthDowntime per year
99%about 7 hours 18 minutesabout 3 days 15 hours
99.9%about 44 minutesabout 8 hours 46 minutes
99.99%about 4 minutes 23 secondsabout 53 minutes

The difference between 99.9% and 99.99% looks small, but it’s ten times less downtime.

What keeps a website up

  • Reliable data centres with backup power and several network connections.
  • Servers with redundant storage, so one failed drive doesn’t take sites offline.
  • Monitoring around the clock, so problems are fixed before most visitors notice.

What uptime doesn’t cover

Planned maintenance announced in advance, and problems caused inside a website (for example a broken plugin) usually don’t count as downtime. Daily backups help with the second.
