Anyone with websites on DreamHost servers (not to be confused with DreamWidth) might want to log into your main account soon.
All FTP/SFTP/Shell accounts had their passwords reset due to suspicious activity detected in the databases last night.
They don't think there was an actual theft of passwords but they're taking no chances.
You will not be able to FTP into your sites until you've gone to your control panel and changed the passwords, though.
Also, WebFTP seems to be down at the moment.
