There is no official position.  I personally use 5.x for almost
everything because there are still more than 2.5 years of support for
5.x, 5.x is very stable, and 6.x is still very new.  However, just from
a "security perspective" either 5.x or 6.x is fine now if you are using
CR.  There are 2182 "6.1" or newer RPMS in the x86_64 CR repo right now.

I certainly use 6.x on my workstation machines ... admittedly they are
not normally directly Internet facing.

I do recommend that people give weight to security and consider buying
RHEL licenses for critical machines, but there are millions of satisfied
CentOS users.

I know several Universities that have deployed 6.x or are going to do so
in the next couple of months.

I know that Dell is using CentOS for deploying application appliances,
Facebook is using CentOS, cPanel uses CentOS in a huge percentage of
their deployments, 8 of the top 500 super computers in the world are
CentOS, and that CentOS is still the most used version of Linux on the


I would also like to point out that the cPanel, Plesk and OpenVZ
deployments of CentOS (about 1/2 of the total deployed CentOS web
servers on the Internet) do not even show up as "CentOS" ... they show
up as "unknown Unix" on that survey.
