site keeps getting down daily

It seems my hosted sites keep getting down for a period of time every day recently. I just set up my sites recently and there is almost no traffic at all. So it couldn't be a load issue.

I attached a report from Host-Tracker.com here. As you can see 2 of my 3 sites were down over an hour yesterday.

Is this expected or something you can fix?

Thanks,

Joe

p.s. I tried to send email to support@dreamhost.com, but got rejected saying I am not a customer, don't know why.

Load issues aren't necessarily caused by you or your sites. As it's a shared server, your lovely co-users often hose up a server. When you're experiencing trouble, be sure to use the panel's built in Contact Support section, as that logs a ticket in the help desk for the appropriate tech.
