Ok, hadn't realised it but i know why its happened.
So you know how i posted about Showdown having a host problem here?
Well Showdown no longer run on CloudFlare. They now run on DreamHost if I remember correctly.
So basically the whole of showdown got reset. Meaning the home page got wiped.
To resolve this Me / HF / Ninja need to talk to Zarel or Cathy to get it added back onto main.
I'll PM Zarel / Cathy after this post.
EDIT: I PM'd Zarel and he put it back up. Thanks for pointing that out.
