Would it be too much to ask Dreamhost to check for the recurrence of this problem automatically, instead of relying ~ totally, it seems ~ on feedback from customers?
Well, perhaps they already have approprate monitoring tools in place. But it certainly doesn't seem like it. If they did, we wouldn't keep hearing things like "For the past few days, I have been experiencing an extremely slow loading of my website" (emphasis added).
As we've established in several conversations here over the last six months, this problem has a very definite signature which is easily and reliably detectable by automatic monitoring tools, which can send an email to the appropriate person within minutes of the problem first arising.
