Rebuilding raid doesn't take the server down but disk performance i.e. IPOS will be reduced while it takes place Running service on 1 server always carries some risk whatever form that server takes For example I have loads of stuff on Linode but always make sure I keep backups off-linode, incase I get a random TOS account shutdown and they stop speaking to me etc
