The average downtime for websites in March was a minute under two hours, according to monitoring site Pingdom. The figure is based on a sample of 2000 sites. Pingdom says that because an estimated 51.3 million sites were live over the month, this represents a total downtime of 4,239,375 days or 11,614 years - a time span that would put us back into the last Ice Age, when Britain was still joined to the continent.

By the same token if the average human sleeps eight hours a night and the world population is 6.59 billion then we doze for a collective six million years each night, which would put us way back beyond the first known proto-humans. Meaningless statistics, but curious nonetheless.
