I just gave Easy CGI a try. So far their response from support ceneter via web support is very quick and got all questions in 5 to 30 mins.

But what I found useful is wembot.com Website Monitoring Service. There are similar website monitoring services, but this one can send out a reboot request email to the tech support of a hosting company you use with your email address so that you can get a reply to your address, and it's done automatically when downtime is detected. I'm currently testing it with 14 day trial, but looks like it's useful.
