Linux distributions keep moving forwards, and as they progress older releases stop receiving security patches or updates. As part of our commitment to maintaining reliable and safe services, we would like to highlight the following announcements...
The CentOS-4 distribution (current version 4.9) will be at End of Life on February 29, 2012.
The Debian project released Debian GNU/Linux 6.0 alias "squeeze" on the 6th of February 2011 ... Hence, the security support for the old release of 5.0 is going to end on the 6th of February 2012 as previously announced.
And in related news CentOS 5 and CentOS 6 support extended by 3 years
We have a selection of upgrade guides available for some distributions
Anyone wishing to upgrade older installations are encouraged to contact us with questions via a support ticket
