Huh. Was curious what kind of discount they provide in case of downtime caused by hardware failure, but it sounds like they didn't even notice. Shouldn't they monitor the basic vitals? Or you simply reacted too quickly?
Monitorering is then your responsibility. They have no login/account on your host.
For any hardware issues I have had I have simply created a support ticket. They have always been really fast at responding and fixing for me. If you report a disk and serial number it gets swapped in no time.
They have managed offerings as well. I have never used those.
