This is the notification of the End of Life (EOL) for CentOS 4.

The 7-year enterprise lifetime of CentOS-4 ends now.  CentOS-4 has been
copied to the CentOS Vault.  The last released tree is available here:


All architectures of CentOS-4 (i386, x86_64, ppc, s390, and s390x) are
impacted.  Support for the CentOS-4 Cluster Server and the CentOS-4
Global File Server (csgfs) is also ended.

The CentOS-4.8 and 4.9 trees will be emptied from the CentOS mirrors in
short order.

CentOS-4 will remain available in the CentOS Vault, along with CentOS-2
and CentOS-3, indefinitely.  You can use the vault in the same way you
have used the CentOS mirrors in the past, however no updates will be
released for CentOS-4 moving forward.

Accordingly, the CentOS Project strongly recommends that you migrate any
CentOS-4 installs to a newer version of CentOS (either CentOS-5 or


If you have workloads that you can not move to a newer version CentOS,
Red Hat, Inc. offers an optional support extension called the "Extended
Life-cycle Support (ELS) Add-On Subscription" for their Red Hat
Enterprise Linux (RHEL) 4 product. The ELS Subscription provides up to
three additional years of limited Software Maintenance (Production 3
Phase) for RHEL 4 with unlimited technical support, critical Security
Advisories (RHSAs) and selected Urgent Priority Bug Advisories (RHBAs). 
This service from Red Hat, Inc. would require both a RHEL 4 subscription
and an ELS subscription. 

Note:  The CentOS Project is not affiliated with Red Hat, Inc.  CentOS-4
is not, nor does it contain, Red Hat Enterprise Linux 4.  However,
CentOS-4 is built from publicly available sources released by Red Hat,
Inc.  Because of these common source files, work loads running on
CentOS-4 should be able to be moved to Red Hat Enterprise Linux 4 and
allow you to use that platform with ELS for an additional 3 years if you
need that service.

Please see this link for more details about Red Hat ELS:
