We are receiving down alerts for VPS's on host5.createhosting.co.nz. This appears to be due to high load, possibly due to a DDOS.
This is affecting multiple Magento and WordPress sites, and does include mail services for those sites.
We are currently investigating and working on this issue.
UPDATE: We will be restarting individual VPS's to isolate the DOS attack. These will be coming online (staggered) shortly.
UPDATE: VPS's and services are all back online. Still investigating with report to follow.

Situation: We just received an alert that there are some security issues in the version of Xen we are using. In the past we have performed live patches to mitigate these without impacting customers, however that is not an option in this case. The severity of the issues warrants we perform an immediate update. The security issues are embargoed until 2020-12-15 12:00 UTC so we cannot release details about the issues before then. We must also fix the issue before the embargo date.
We will be updating our host servers (requires a VM restart) to apply Xen security hardening, and bug fixes.
Customer action required: None at this stage. Now would be a good time to ensure that your VM works as expected after a restart (that services are automatically started on boot up, etc).
Who is affected: Customers running VMs on our Xen hosting stack including VMs on shared hosts and VMs on dedicated hosts.
Detail: Engineers will be updating our host server software stacks to the latest version of our Xen virtualization software, the most recent Intel microcode patches, and a more recent Linux kernel for the host. To do this we will be stopping the VMs on host servers, updating the software and restarting the servers. VMs will then start up as normal.
Note that we will not be making any changes to the VM file systems.
The software update process typically takes 20-60 minutes per server if all goes well. 45minutes is pretty typical. Hosts with lots of VMs take towards the longer end of that range. We reserve a 2 hour window for the upgrades.
