공지: 서버 node maintenance, 오늘 밤 20-30분 다운될 수 있다네요

오늘 초저녁에 다음과 같은 공지를 받았는데, 까먹고 있었네요 ;; 

사이트가 20-30분 정도 먹통이 될 수 있으니 놀라지 마시라구요. 

This is a notice to inform you that the parent hardware node that provides service to your server will be rebooted on June 6th between 23:00 and 2:00 CST for an important kernel update. There should be no more than 20 to 30 minutes of downtime to complete this upgrade and reboot the hardware node. All best practice methods will be used to ensure a quick reboot after the kernel update to minimize downtime on your server. This maintenance window is required to reboot the hardware node into the most current Parallels Virtuozzo kernel. Updating to this new kernel will address critical bug fixes to the parent hardware node.

We apologize in advance for the short notice and any inconvenience that this Hardware Node maintenance may cause. This critical bug fix within the kernel requires us to put this update in place as soon as possible.
