Dedicated Server customers with a manged service plan will be updated over this weekend to ensure that servers are running the latest kernel version, 2.6.18-53.1.14. Information
on the specific vulnerabilities being patched can be found at the following links:

Additionally, there are security and enhancement updates available for various packages. These updates may have
already been applied to your system; if they have not, we will ensure during this session that they have.

Most users will not notice any interruption in service.
For the remainder, a reboot of the server, which entails approximately 90 to 120 seconds of downtime in most cases, is required for servers to run the new kernels.
