Hello,
Linode has received a Xen Security Advisory (XSA) that requires us to perform updates to our legacy Xen host servers. We must complete these updates before July 26th. For general information, please see our status page post below:
https://status.linode.com/incidents/dgzvdyqttr9f
Your Linodes have been assigned a maintenance window in which a reboot will occur. These times are listed within the Linode Manager[1] in the timezone set in your user's My Profile[2]. Your schedule in UTC timezone is as follows:
* 2016-07-22 11:00:00 AM UTC - linode951847
Upgrading to KVM will allow you to avoid this maintenance entirely. You can use the “Upgrade to KVM” link in your Linode’s dashboard to move to KVM. Please note that KVM upgrades are not available in Tokyo at this time. More KVM upgrading information can be found here:
https://www.linode.com/docs/platform/kvm-reference
We strongly recommend you read through our Reboot guide, which will help you prepare your Linode for these reboots. After going through that guide, we recommend you reboot your Linode at a convenient time to ensure your services come up correctly. The Reboot guide is available here:
https://www.linode.com/docs/uptime/reboot-survival-guide
During the maintenance window, your Linodes will be cleanly shut down while we perform the updates. Your Linodes will be inaccessible during this time. A two-hour window is allocated, however the actual downtime should be much less. After the maintenance, each Linode will be returned to its last state (running or powered off).
Please let us know if there is anything we can do to assist.
