We received notice this afternoon that our provider, Rackspace, has identified a vulnerability in Xen Hypervisor. This vulnerability has been patched by Rackspace but it requires a reboot of cloud servers in order to for it to take.
You can read more about the vulnerability and requirements here:
We have elected to reboot cloud servers in our network at our discretion rather than allowing Rackspace to reboot using a maintenance window approach.
We will begin the process of rebooting cloud servers tonight, May 13th, at 10:00 PM Central time. We expect this process to take several hours and customers will see intermittent outages of varying length.
We will update this page when the maintenance is completed.
If you have any questions or concerns, please contact our help desk.
We apologize in advance for any inconvenience this may cause and are working toward addressing this as smoothly as possible.
UPDATE – May 14th, 2015 @ 2:57 AM Central: We have completed the reboots that are necessary as a part of this vulnerability patch. All systems are back up, running, and stable. Thank you for your patience and please let us know if you have any questions. Thanks!
