I hate to say this but I think DreamHost is as bad as the last temp host in the UK. The server is speedy compared to the last host but it keeps vanishing for extended periods.
Unfortunately, connecting with your new web host's network has been inconsistent since you moved. This is not related to your domain name because I timeout 2-3 hops before the connection even reaches your server. I couldn't access your site a couple hours ago, and 2 times yesterday. When it vanishes, it lasts a long, long time. This never happened w/your original host, and it's not normal. I have experienced this problem 3 times in the last 24 hours, and each incident occurred hours apart, so it wasn't back-to-back. I tried to post 5 or 6 times yesterday, but I could not post 2 messages because I submitted the form to find the site was gone. I couldn't even recover my posts by going backwards, and I'm too lazy to type them again.
To ensure the outage issue wasn't related to your domain relocation, I did a trace w/your IP address using VisualRoute's server in New York. I did a trace when the site vanished to be sure the problem was not with my provider. Although my browser would timeout trying to connect, VisualRoute's New York server could connect with your IP but 10% to 50% of packets were lost when VisualRoute connected to DreamHost's network. Unfortunately, I did not do screenshots when the packets were being lost but I tried again when the site was up to see the response time, and there are consistent problems with the network even when the site is speedy & visible.
Unfortunately, there are instabilities w/DreamHost's network which likely causes a failure and restart after a certain period of time or during peak activity on their network. Even when the connection appears speedy from my side, VisualRoute shows the connection as becoming erratic upon entering Dreamhost's network. I took these screenshots to show you:
