I've had such a bad experience with this hosting company that I can not but share it with everybody so it doesn't happen to other people.

On how CWIHosting screwed my sites for a week
In brief: CWIHosting just kicked me out one nice day without any previous warning, and then they held my data from me so I could not move to another hosting company (I made the mistake to keep my database backups in the server). Instead, they proposed that I pay 8 times more to get a dedicated server with them, as the only way for me to get access to my data (and even to my e-mail messages!).
This is definitely not a professional behaviour and can render your site anavailable for well over 4 days! and cause you a lot of trouble and desperation. So my advice is: do not hire any services from CWIHosting.com
