Web Hosts & Uptime

Here is a great chart of web hosts downtime:

% Available – Downtime/year
98% – 7.30 days
99% – 87.6 hrs
99.9% – 8.76 hrs
99.99% – 53 mins
99.999% – 5.25 mins
99.9999% – 31 secs
99.99999% – 3.1 secs

When web hosts promise you 99% or even 99.9% uptime, realistically they a promising you a headache.

Knock on wood, we have been well above 99.99% downtime for the past year (that is around 4 minutes per month). Our only downtime has been late night reboots to install required patches / security fixes.
