I don't know what the cost is, but it must be significant. I work for my state's health department, so downtime means things like the testing of biological samples isn't happening, or cannot be capture even if it is happening. People can't start their work, etc. It must be quite big. It's complicated and often outages aren't our fault, so much as suppliers of infrastructures. For example, the State uses CenturyLink, so when CenturyLink's down, that affects all of us, state wide.
