We will have rolling reboots of Oakley, Ruby and Owens clusters starting from Monday Feb 5, 2018 to address recent CPU vulnerabilities. Login nodes will be rebooted first. The rolling reboots won't affect any running jobs, but users may experience longer queue wait time than usual on all clusters. We apologize for any inconvenience this may cause you. Please contact firstname.lastname@example.org if you have any questions.
