Why Cant they find my site?

'The page cannot be displayed' since I went to DSL

When I type in a few of my domains, I keep getting this message:

The page cannot be displayed

The page you are looking for is currently unavailable. The Web site might be experiencing technical difficulties, or you may need to adjust your browser settings.

What is causing this? The site should work!. I have other sites on the same host so It wouldnt be that would it? I get this error alot. Is is my connection or something? Or is it the website?

ask them ping the domian
to see if it's resolved
and ask their ip, then trhy tracert -d to the ip from the server, if u can't do it, ask network administrator for help

Would this have anything to do with my computer/settings? This happens to sites when I am browsing. I used to have cable, now im on DSL and its slower, and I get these page canot be displayed/cant finder server things all the time now
