>One key thing to note: Ubuntu isn’t seeing a 599 percent increase in additional users. That jump represents its increase in overall operating system market share from month to month. But it’s still an astonishing number

So... a whole bunch of servers using Ubuntu got fired up?

The numbers being reported are based upon visits to websites which are part of the NetMarketShare data collection network, so a bunch of servers using Ubuntu getting fired up wouldn't account for the increase.

An increase in market share higher than the increase in actual users would be accounted for by the size of the market overall decreasing while the number of Ubuntu users either stayed the same, increased but at a lower rate than the increase in market share or decreased at a rate lower than the decrease in the number of users of other operating systems.
