I hate to say it, but I'm got to agree with pmn-jjb. The service and the support have been awful lately. My VPS goes down daily, I rebooted it 5 times yesterday. And that's just because I happened to notice it down, I don't know how long it was down when I wasn't around (that'll teach me to take a day off!) The support has been bad lately, really bad. I sent four support emails last night, and didn't get a reply until 4:00pm today. 16 hours. That's just unacceptable. The reply I got basically said they've got so many problems that they are trying to deal with they don't have time to monitor support or Twitter. Which is scary.
I have hosting at two other places, and don't have issues like that there. I've been a customer here since Feb. 2008, and I've been recommending DreamHost for years, and have brought them dozens of customers. And I'm pissed that I should move my sites away - I used to LOVE DreamHost.
