Technical Information

Technical Information

Work summary
The Wake-on-LAN server is currently in a state of supressed security patching to limit impact to production services during Change Freeze. Now that Change Freeze is over we are bringing our production services back into line with the standard security patch schedules. This should result in a small number of package updates. They do however need a reboot to install a new kernel which was released during the change freeze. As the Wake-on-LAN server is a single host there will be service interruption during the reboot. This should last 5-10 minutes
