I have Windows VPS hosting with blacknight where I host some clients websites. I have been experiencing issues recently where the vps has become unavailable, it has become more frequent and more and more frustrating. Does any one know of any software or service in which I could be alerted when my VPS becomes unavailable? Or when a site on the VPS becomes unavailable? At least this may mean that I could have the issue resolved before the client notices! Not ideal, but its a start while I try and resolve the issue why the VPS becomes unavailable. Any suggestions/assistance would be great.
