We are experiencing some issues on WinVPS43 with auto reboots on a regualr basis. We are attempting to resolve it ASAP.
This is new hardware that has some clients from WinVPS15 and WinVPS33. (but not all)
We will update here as we know more. For the time being we may have to shut down some VPSes to find the cause and resolution, and will start them back as soon as we can.
Right now we are working with it successfully by starting limited numbers of VPSes(aka 1-2 only) and migrating them to other nodes live. We hate having to do this but have not much choice since sometimes even reboots after just 7-10 minutes up.
