I'm seeing this more and more frequently on my site and I'm unsure if its something I've done wrong with the site or if its just randomly becoming unavailable because I'm using the free site at the moment or what. http://shadow-realm.tk/
This is my site.
This is a screenie of my site being down message I get when I attempt to visit it:
This doesn't happen at any particular time and it can work again just moments later or even on the next refresh.
Your assistance with this issue is much appreciated. Thank you.
