The morning of the first Wednesday of the month is designated as a maintenance reboot window for some Linux servers. Linux servers can be automatically rebooted by taylor or chef, or they can be manually rebooted by a unix-admin team member.
This monthly reboot schedule facilitates the patching and activation of updated kernels, glibc, and other shared libraries on Linux servers. Periodic reboots to enable security patches are required by SLAC Cyber Security and the Department of Energy.
The first Wednesday of the month Linux server reboots are staggered between 1:30 AM - 7 AM Pacific Time for automatic reboots by taylor and chef, or 7 AM - 11:30 AM for manual reboots by a unix-admin team member.
If you would like to add any servers to the first Wednesday of the month reboot list, please email unix-admin@slac.stanford.edu, and indicate if you would like your server to be automatically rebooted by taylor or chef, or manually rebooted by a unix-admin team member.
