Dreamhost tech support gets a A+ for heart, an F- in every other measure.
Many hosts either have a phone number or they turn urgent tickets around in under 15 minutes. At least a "we know about the problem and we're working on it."
Dreamhost is great when things are good, and...well, I'll probably get edited if I say how they are when things aren't working. Like right now for me...every single website I have is unreachable and the support system says "resolved." Yeah, right.
