Just a reminder that this is a customer-to-customer forum.
I've had some questions answered late at night, so I know there's at least someone around 24 hours.
I suspect it's a matter of submitting your questions at the appropriate category. I know that DreamHost is based in Los Angeles and so their most highly skilled technical resources will only be generally available during "tech business hours" in the US Pacific timezone - notwithstanding any night owls. I'm sure they have support staff working 24x7 and I'm also sure that they have lots of folks on-call 24x7.
What kinds of questions are you asking and at what priority?
Finally, remember that I'm just guessing from what I know about the company I work for (not DreamHost). I don't know their operational support plan.
