I don't see how faster updates translates to higher uptime.

For what it's worth, paid versions may have benefits in terms of better
thought out security or dedicated infrastructure (not so much in terms of
bandwidth, but that responsibility is all under one entity).  As an
example<http://www.cs.arizona.edu/%7Ejsamuel/papers/cappos-samuel-baker-hartman-ccs08.pdf>,
commercial distributions like RHEL and SLES are protected from certain types
of attacks against package managers simply because mirrors are hosted
internally, whereas CentOS is open to abuse from malicious mirrors.

P.S.  I'm not doing anything malicious on my mirrors ;-)
