These hypervisor upgrades have been successfully completed, including to Linux Kernel 7.0.14-4.

Many thanks for your patience as we ensure continued platform reliability.

We’ve completed these works for Corporate, Radio and Colocation machines.

It has not yet been completed for Managed VPS machines due to a CloudLinux bug.
We’re waiting for their team to resolve the update blocker so we can proceed with works.

Began
Updated

G’day,

Please note that these upgrade works will also address a guest-to-host escape vulnerability & root vuln:

Januscape was used in January 2026 at Google’s kvmCTF as a 0-day, after laying dormant in kernel from 2011.

As always, thank you for your patience while we work to ensure continued reliability, security & performance.

Cheers,
Merlot Digital

Maintenance Planned

G’day,

Following successful testing, we’ll be performing sub-major upgrades to all production hypervisors. If assistance is required, we have smart-hands on-site 24/7/365 who can assist should OOB be insufficient to recover.

A single node at a time: guests will be powered off softly, the node upgraded to the new major versions & rebooted, and then only once testing is successful guests will be started up gradually & returned to service.

Bundled in with many nice changes is the formal introduction of Rust into the Linux Kernel. It has been there for a while with the experimental tag which has been removed as of v7, showing its weight alongside C.

Please let us know if you’ve any queries or concerns about these works.

Cheers,
Merlot Digital
