We are updating the kernels on all the OpenVZ servers so that our servers can support popular modules like PPP for VPN related software. For the longest time we were unable to support PPP due to it being in "experimental" stages and never supported by openvz kernels. Until recently, it is now supported and we too would like to support if or our clients.

Kernel upgrades will require each node to be rebooted. You may have to restart your VPS in the control panel after the reboot. These kernel updates should only cause roughly 1-2 minutes of downtime.
