Site not working
There could be a number of reasons why your site was suspended.
Firstly, google robots come by every once in a while to check out the pages to see if there's inappropriate content or if the page loads quickly or works properly etc. It might have been a case where the last time a check was done, the site was down for maintenance. The only issue i can see right now is that the page takes at least 15 second to load and I had to refresh the page a few times in order to see the content.

I hope this helps!
