We will be updating kernels for, and rebooting all Centos 6 and Centos 7 servers under our management, excluding hypervisors, highly available clustered applications, and servers owned by customers with chrome maintenance schedules.
This is to protect against the follow remote DOS exploit, that leverages vulnerabilities in the Linux kernel to deny services with any appropriately modified TCP packet: https://access.redhat.com/articles/3553061
Impact Of Work:
Customers whose servers are being updated may notice 2-8 minutes of downtime, typically. We will be monitoring for any server that takes longer than this to boot up and regain services.
Servers will be updated and rebooted 3 at a time.
If you would prefer to schedule your server reboot to occur at a specific alternate time, and have confirmed that you have one or more Fully-Managed Centos 6 or 7 servers, please reach out to support@anySiteSolutions.com, or submit a ticket via https://portal.anySiteSolutions.com, and specify your desired alternate update time.
