Do you often experience the downtimes?
Not at all. If/when it does go down, it's a rare thing.
If the downtime is more than 10 hours, it is better to change hosting company.
WebHostingWatch shows the real uptime of such companies as Hostgator, Fatcow and Greengeeks.The uptime is not 99.9 % as this is written on their site.
Better to change hosts if its more then 12 hours then they have issues solving probablems quick..

I agree with you that it is unacceptable when the downtime of the server is more than 12 hours. When a reliable hosting company experiences such downtime, they should have a backup server in order to switch the crashed server into the backup one quickly.In this case, the downtime is minimum and the sites of the customers are working properly while the support department is working on resolving the issue on the server.Better to change hosts if its more then 12 hours then they have issues solving probablems quick..
To determine the real uptimes , WebHostingWatch specialists were investigating the sites from different hosting companies during two months in different time periods.The results were different, but they really proved that the hosting company real uptime can't be 99.9%.Please explain how WebHostingWatch measures their servers. The uptime percentages most providers publish are often not actual uptimes of their servers, rather their SLA guarantees.
