[sigh] Seems like every time you turn around.

Linux Foundation infrastructure including LinuxFoundation.org,
Linux.com, and their subdomains are down for maintenance due to a
security breach that was discovered on September 8, 2011. The Linux
Foundation made this decision in the interest of extreme caution and
security best practices. We believe this breach was connected to the
intrusion on kernel.org.

Kernel.org says only, "Down for maintenance." Here is a cached page from Google.


Security breach on kernel.org

Earlier this month, a number of servers in the kernel.org
infrastructure were compromised. We discovered this August 28th. While
we currently believe that the source code repositories were
unaffected, we are in the process of verifying this and taking steps
to enhance security across the kernel.org infrastructure.

What happened?

    Intruders gained root access on the server Hera. We believe they
may have gained this access via a compromised user credential; how
they managed to exploit that to root access is currently unknown and
is being investigated.
    Files belonging to ssh (openssh, openssh-server and
openssh-clients) were modified and running live.
    A trojan startup file was added to the system start up scripts
    User interactions were logged, as well as some exploit code. We
have retained this for now.
    Trojan initially discovered due to the Xnest /dev/mem error
message w/o Xnest installed; have been seen on other systems. It is
unclear if systems that exhibit this message are susceptible,
compromised or not. If developers see this, and you don't have Xnest
installed, please investigate.
    It *appears* that 3.1-rc2 might have blocked the exploit injector,
we don't know if this is intentional or a side affect of another
bugfix or change.
