Thanks man! That saves me a bit time and I don't need to use my dedicated server for hosting the site itself. Never tried to use the local version in that way, but seems to work great :)

I registered a new hosting server with a different provider, copied everything to over there and started the domain transfer (was registered with my old hoster).

They say, it can take 1-5 business days until the transfer will be done, so steemworld.org should be reachable again on monday/tuesday. I can't setup the SSL certificate prior to that, but everything else is ready to go.
