site:example.com shows nothing

I have 3 years old web site, has about 10.000 pages indexed in google. Today
site:mysite.com shows nothing (all datacenters)
link:mysite.com shows url's as normal
pr is 3 (all datacenters)
still in google directory but shows pr 4 ( never been pr 4 before)

google webmaster tools say;

I haven't changed anything in the site for about 6 months except publishing new unique content. There is no outgoing links except wikipedia

I am really confused, banned or not?

 

What is the URL?

 

Try site:www.mysite.com instead.

 

That's very odd - give it a day and see if the pages come back. Google has been performing some very odd dance steps over the last 2 months.

 

Have you gotten a lot of new links to your site lately?

 

it looks that your site is banned but if you write your url, it will easy to make comment
