I have had a job where my small, internal tool, for debugging purposes, had to be deployed to a minimum of 3 datacenters. I had 2 of them in the US and one in Europe, and was asked to move one of the US ones to a datacenter that was in another coast, cause who knows, maybe an earthquake will knock off all of the US west coast. That is the paranoia level necessary to achieve crazy high uptime.
