Server Not Found: Can't access website, admin, FTP or cPanel

Hey Guys,

I was just doing some work for a client, and I went to their page to log in – it came up fine. I put in the log in details and it failed twice, so I clicked on to reset the password (I was putting in the right password) and then all of a sudden, the website went down, and I couldn’t log in to the ftp or cpanel – it all seems to have gone.

It happened about a month ago too – but that seemed to be a problem with the host (who is a pain in the butt).

Do you think this is a WordPress problem or something to do with my host?

Thanks
