Hi, I've got a bunch of micro niche site, hosted on three different web hosting servers. I am scared at the idea of losing ranking on search engines or getting penalized in case of persistent downtime affecting one or more of the servers. How could prevent this issue? Do you know any service that can help me to keep my sites up in case of critical downtime? I already use mon.itor.us to be informed of potential problems, but it's just a monitoring tool.
