What does 99.99% uptime mean?

Uptime in minutes

Uptime	Downtime per month	Downtime per year
99%	about 7 hours 18 minutes	about 3 days 15 hours
99.9%	about 44 minutes	about 8 hours 46 minutes
99.99%	about 4 minutes 23 seconds	about 53 minutes

The gap between 99.9% and 99.99% looks small, but it means ten times less downtime. For a Rwandan shop taking orders late in the evening or a school portal on results day, those minutes count.

What keeps a website up

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

What uptime doesn’t cover

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