In accordance with our Upstream Vendor's Errata Support Policy, the regular life-cycle of Scientific Linux 4 will end today, the last day of February 2012.
After today's date, The Upstream Vendor will discontinue their regular update services. We must follow them in this matter. Therefore, new bug fix, enhancement, and security errata updates will no longer be available for Scientific Linux 4 after the End of Life date. They will not be providing updates and so we cannot provide them. Anyone still running production workloads on Scientific Linux 4 should be aware that after today no updates of any kind will be published. Because of this, we hope everyone has completed their migration to Scientific Linux 5 or Scientific Linux 6 by now. The existing Scientific Linux 4 directories will be archived in April 2012. People wishing to obtain a personal archive of Scientific Linux 4 can do so during that window. Again, this is a reminder of the end of life for Scientific Linux 4. - Scientific Linux Development Team
