Today a huge number of VPS providers got attacked with a zero day SolusVM exploit early this morning. It was bad, I mean real bad.

So I guess now its time to look more at Proxmox. An open-source virtualization management solution for servers. It is based on KVM and container-virtualization and manages virtual machines, storage, virtualized networks, and HA Clustering.
It means its FREE.
