Today as soon as i saved my blog and clicked its preview, i was shocked to see that there are no blogs on my url. I got confused whether i saved them or did something else ?

I refreshed my page again and again, but all in vain.  

Then i went to rocky’s and kunal’s blog to find the following:

After that i concluded that its not happening with me only, it was some problem with wordpress.
