I've had hard drives go bad in a huge variety of different servers in many different locations. The Planet (now Softlayer), Digital Ocean (VPS ...), NAC.net, Atjeu, and others. These days I just expect it to go bad, so I use ZFS within FreeBSD to watch for errors, and when they happen I ask them to replace a single drive, and then the other. So far it has worked very well for me with no data loss. I've been fairly lucky in that both drives have't failed at the same time.
