Web Host - Uptime
Uptime refers to how often a site is available or responsive to web requests.
The internet never sleeps, which means your web site needs
to be up every second of every hour of every... you get the idea. A visitor
could be arriving at your site's home page at any time of the day, so a web host
with a high uptime percentage is critical.
Nearly all web hosts will advertise and guarantee a "99.9%" or higher uptime percentage.
However, these guarantees are about as trustworthy as a used car salesman, not very! If
a host has a history of a great uptime performance they will post a history
of their uptime performance, monitored by a 3rd party, such as
Alertra or InternetSeer.
Additionally, web hosts that operates on a redundant network (more than one data line to the internet)
will be more reliable than a web host that is running
only a single data line.

web site needs to be monitored more closely, both

pay for monitoring plans that are very thorough.
