Let's suppose that we have three vps containers with untouched operating system on different virtualizations such as KVM/Xen/OpenVZ Each vps containers are hosted with different providers.
After a month all of the vps containers went down. All vps providers has reported that data on vps was corrupted for unknown reasons. Providers didn't find the issue on their side as they said that they are using Raid 10 setup or etc.
What's the possible reason that data was corrupted on all three vps containers ? Vps containers weren't used at all. Is virtualization type makes sense when a data is lost ?
Thank you.
