Here is a hosting service that you will want to check out! www.Hostorix.com
This service is different than most hosting companies out there as it provides “Fail Over” technology.
What that means is that your data is copied to two different servers. Not two different hard drives but a completly different server.
What’s so good about that? Well if one server ‘fails’ you site is still up because it automatically redirects the traffic to the other server so that you are still making money.
Once the failes server is restored all data is synchronized between the two, all with out down time to your web site.
With Hostorix hosting it gets even better. You can host all the domains you want on single account using Addon Domains.
