Server Uptimes

[HSWeb]

Hi Guys,

Some of you might find this helpful. It's a server uptime table.

All calculations have been done over 31 days. From 99.9% Uptime to 99.5% .

Percentage uptime: 99.9%
Server Uptime: 30 days 23 hours 15 minutes 21 seconds
Server Downtime: 44 minutes 38 seconds

Percentage uptime: 99.8%
Server Uptime: 30 days 22 hours 30 minutes 43 seconds
Server Downtime: 1 hour 29 minutes 16 seconds

Percentage uptime: 99.7%
Server Uptime: 30 days 21 hours 46 minutes 4 seconds
Server Downtime: 2 hours 13 minutes 55 seconds

Percentage uptime: 99.6%
Server Uptime: 30 days 21 hours 1 minute 26 seconds
Server Downtime: 2 hours 58 minutes 33 seconds

Percentage uptime: 99.5%
Server Uptime: 30 days 20 hours 16 minutes 48 seconds
Server Downtime: 3 hours 43 minutes 12 seconds

You can also calculate it using this method:

To the minute:
31(days) x 24(h) x 60(m) = Time
Uptime % = ((Time - Downtime(in Minutes) / Time) x 100

To the Second:
31(days) x 24(h) x 60(m) x 60(s) = Time
Uptime % = ((Time - Downtime(in Seconds) / Time) x 100


Hope this helps someone out there.

Wikipedia has a table with all of this info at http://en.wikipedia.org/wiki/High_availability#Percentage_calculation

I don't bother working it out manually anymore.
