Illuminati Google are not letting me create a new blog.

I tried to create a new blog today, with the title: The Illuminati: all big business is run by the Illuminati.  When I created the blogsite title, and tried to create the blogsite address, I was prohibited from doing so, with a message coming up saying: this blog site address is invalid or unsupported.  I then tried to create a new blog with a random title such as dddd and a blogsite address with just one random letter.  The same still came up. Then I tried a simple title like Andrea Hudson Piano, with the same results. I also tried to access my present blogsite address at www.nhsmentalhealthservices.blogspot.com with google chrome and found a page saying: this webpage is not available. The server at www.mentalhealthservices.blogspot.com can't be found because the DNS look-up failed. What an earth is the DNS look-up?
