I finally moved away from DreamHost problems and over to MediaTemple. And like Mark Wiens, I too am on The Grid.
Moving was simple with WordPress Database Backup, I just downloaded a backup of my blog/site and then uploaded it into PHPMyAdmin and everything was set (with the exception of updating my .htaccess file).
Even though DreamHost offers a lot more than MediaTemple in terms of storage and bandwidth, I am certain I am never going to come close to reaching the max so those extras become irrelevant. What is relevant to me is reliability and trustworthiness and DreamHost lacks both.
