Help! What's wrong with my site?

My website,
was just created a few days ago, but this afternoon it was working, and then it slowed down drastically for a few moments, and now it simply won’t load. I know for a fact that there is no traffic, so what is the issue?

I did the test on the control panel, and nothing showed up. When I try to publish by website from rapidweaver it can’t even connect to the dreamhost server…

any help?

It’s super fast for me. Next time it’s slow, log into your shell account via SSH (or PuTTY) and do the ‘uptime’ command to see the load averages. They should be below 5.
