I sat that the other day and on the phone with a friend of mine who hosts with DreamHost, she put in a ticket about 7am and nothing til almost 8pm that night. Her entire site was down, for the most part - its a business site thats run with forums so her index page shows (they rub VB for the boards), the calender worked and who's online - everything else was a table lost error.

Its really hard to help calm down someone when they are not hosting with you, its not like you have any idea what exactly is going on w/o being able to peek inside, but once everything did come back up it was a huge PITA since they lost 12+hrs of data doing a restore, good thing for backups. Seriously though if someone had me waiting 1/2 a day for a support ticket reply (even a "We are working on it") I could be happy with that, but nothing for 12+ hrs I would FREAK OUT.
