I am also using forexvps, and much satisfied.
I've put my MT4s in startup list, so incase of reboot, it should restat MT4s.
I am also running a notepad application, so that incase of reboot, this will not restart, and I'll check the reboot manually.
After all these measures, I've checked that it has never rebooted in the market hours, for the last 3 months.
I just manuall reboot it on sunday.
