Are you on the 'Alvarado' server too?
I am on the 'Bixel' server and over the last few days I have noticed a few outages lasting only 10-15 minutes each. During these outages FTP and SHELL access are not affected.
I guess DreamHost is feeling the pressure from all the recent sign-ups. I am sure they'll get on top of things soon and everything will return to normal.
