WordPress Name Resolution Error

Hi there,

So I was just adding a post to my WordPress site, and all of a sudden it went down and I can no longer access it. I’m hosted with GoDaddy and the site is: roundreviews.co.uk

In Chrome, when the page doesn’t load and I click ‘More’ it shows:

Error code: ERR_NAME_RESOLUTION_FAILED

I can no longer access the wp-admin, or the site itself. FTP also no longer works.

Any idea on how to get the site back up and working?
