My Box went down for almost 36 hours.
Submitted a ticket and got replied by Dennis Ross:
I will check this issue and update you back on this
few hours later I asked again its status, got replied
It looks like the VPS configuration files seems to be corrupted and are refused to boot it up. We will recreate the VPS and update you the details.
another few hours, still waiting further updates
I'm on OpenVZ, luckily this's not the main box.
Anyone having the same issue (configuration files corrupted) and is it normal to have our box down for almost 36 hours.
Thanks for anyone who lightened me up. :)
