Meltdown/Spectre patching notification - Southfield, MI

Date and Time: Fri, 12 Jan 2018 00:00:00 -0500 EASTERN MAINTENANCE TYPE:

This Saturday January 13th, 2018 between 10PM-11PM EST, we will be rebooting all host nodes serving Managed Cloud Servers to execute new patches against the recently discovered Meltdown and Spectre exploits. You have noted in recent news that two vulnerabilities have been discovered in nearly all CPUs, ranging back to the development of speculative execution on modern processors over 20 years ago. Although both attacks are based on similar principles, Meltdown allows malicious programs to gain access to privileged parts of a computer's memory, while Spectre steals data from the memory of other applications running on a machine. Nearly every modern computer in use is vulnerable at some level. Patches were recently produced to mitigate these two issues on Linux and Windows hosts, and these patches have been generally accepted by the computing community at large as being an effective method to ensure that the exploit is ineffective. At this time there is no evidence that the exploit has been applied to gain access to other systems, either on our host nodes or elsewhere. Due to the grievous nature of these attacks, we are updating all Managed Cloud Server host nodes this Saturday and rebooting them immediately to execute the new patches. With no live patching options available at present, a reboot of the host node is mandatory in this situation. We apologize for the inconvenience that you will experience due to this emergency maintenance, however, please note that we are committed to the utmost stability and security of your virtual machines. Please note the following: - All Linux Managed Cloud Servers will be gracefully shut down, similar to how the "shutdown -h now" or "halt" command works inside your server’s operating system. - This update and reboot action will make absolutely no configuration changes to your servers whatsoever. - Barring any unforeseen issues, we expect no more than 30 minutes per host node to reboot. This is the time for servers to shut down and host node to complete a reboot; your servers may take a bit longer to boot after the host node comes back online. Your patience is appreciated! If you have any questions or concerns regarding this, please open a ticket with us or contact support at 248-686-2000. Kind Regards, Your UBX Cloud Team
