The servers of the web host should be reliable and should have a continuous uptime of a minimum 99.5%. The server reliability translates into the availability of your website on the net. If someone tries to access your site and they get ?server not found? message too many times, they will shift their business elsewhere. A good web host will guarantee 99.8% uptime round the clock 7 days a week.

Traffic Transfer or Bandwidth: Traffic transfer or bandwidth refers to the capacity of the web host to accommodate simultaneous access to your website. This is measured by the bytes number (amount) transferred by your site when web surfers access your site on the web. All web hosts will charge for this service and there is no such thing as ?limitless bandwidth?. It is good if you can find out the details before hand so as to avoid bad surprises with high bills for data transfer. A simple website will be comfortable with about 50 GB to 100GB.
