On October 1 at 10PM CDT, we will be performing reboots of (3) hypervisors in the Cloud01 zone to install patches and other updates. We expect the cloud servers on those nodes to experience an outage of no more than 15 minutes. Some cloud servers that have not been rebooted in more than 180 days may go through an fsck (for Linux users) which may delay the boot time until it finishes.
