Googlebot can't access my site ???

[fivestarmusic]

my site ranking suddenly drooped form top 10 to out of list now, though it was in top 10 from last 3 months and the total number of keywords is 40.

What would be the reason please help me to out of these stages.

Now i found in google webmster tool the following error.

"Over the last 24 hours, Googlebot encountered 52 errors while attempting to retrieve DNS information for your site. The overall error rate for DNS queries for your site is 5.5%."

Google is telling you what the problem is. Your DNS is broken. Without the domain itself I can only speculate. Here's a couple of possibilities

1. You forgot to renew your domain and your registrar has changed your DNS servers
2. Your DNS servers have gone down

I would suggest using a tool like http://www.intodns.com/ to see what issues come up.

I believe Your site should be recovered in next crawl (if DNS issue have been rectified )
