Hi Steve,
Soon we will be migrating your VPS to OpenVZ 7, the next generation of OpenVZ with higher performance and better features. No action will be required from your side, though we thought you might be interested in what will happen behind the scenes - please read on.
As a technologist you likely know that OpenVZ virtualization had lingered for years. Quite recently OpenVZ 6 became an end-of-life product. Don’t worry though, as HostUS continues to receive kernel patches. The old kernel version (2.6.32) and more popular open source packages requiring newer kernels have made OpenVZ 6 a less desirable hosting option. If you wanted to run Docker you have had to use our custom (and old) CentOS template or move to more expensive KVM virtualization. If you wanted to secure your VPS from attackers, and do it without quickly overloading your server with iptables rules you just couldn’t run ipset (the preferred high performance and modern companion for iptables).
