No, your site is not "shut down" in any sense of that phrase. You just never completed the site restoration.
When I go to your site I see the restoration script.
Visit your site, you'll see the restoration script, keep on clicking Next until you reach the last page. Then read what that page says and do what it tells you to do.
If you have a specific problem restoring your site please give me the exact error message so I can help you.
