I now have all of my sites running at Dreamhost and everything seems to be running smoothly. My bandwidth limit is now 64G/month vs. 20G/month at my previous host and is shared by all of my domains. With my old host, I had to allocate a fixed portion of the bandwidth & disk space to each domain.
I had a hard time getting the database for WorldBeatPlanet. After the crash, they initially restored a backup from June, but I finally got them to restore a newer backup, which I copied to the new site.
