I see your problem with the units in the graph. It has been taken from
one of our standard reports, where it is explained, but it should have
been pointed out in the article too.
This is the complete report:
The unit is percentage of market share amongst Linux distributions.
Thank you Sam, that makes sense.
If you change the time frame, you can see older data:
don't have data earlier than Oct 2009, that's when we started our
That is still not what you want in terms of verifiability. As it says
in the article, Debian is used by 9.6% of the websites. We explain our
methodology here: http://w3techs.com/technologies. We use the Alexa
top 1 million sites as a sample. We do this in order to minimize the
impact of spam sites, e.g. someone building thousands of identical
"sites" as a link farm, which could cause wild fluctuations.
It would be good to clarify all that. But OK, I get the idea.
Publicity team, looking at the trend from October 2009, we see that
CentOS and Debian have been pretty close all the time. But indeed,
CentOS goes above Debian in Summer 2010, and just went back slightly
below. My question is whether this is a sign of a trend, or just some
temporary fluctuation. Why does this happen now? The graph shows CentOS
going over Debian during a 6 months period of huge share growth from
April 2010 to October 2010, where Red Hat Enterprise Linux almost lost
as much market share. Can such a quick change be explained?
I'm thinking that presenting the statistic could be interesting, but an
interpretation would be much better.
For what it's worth, if CentOS is considered the same as Red Hat
Enterprise Linux, then Debian is still by far in second place.
hope that helps.

Thank you Sam,
this is interesting, but in terms of verifiability, the graph is
lacking units on the y axis.
I would be curious to see a graph over a longer time frame too.
