mysql5.5

After a call from a customer to say that his website is down, I find that MySQL on our RackSpace Cloud Windows 2008 server was not running. I restarted MySQL but got the 'Access denied for user' error in the browser for all websites with MySQL database. When I look in MySql Server 5.5/data there are no folders other than mysql and performance_schema. It appears all the databases and data have been wiped. Does anyone know what might have happened and where the data has gone? To top that I just found this server is missing from our backup service.

ps appears to be after windows update at 4:01 this morning.
