What's your host file to do with that? That file only comes into play when request originate from your box. For us outsiders you would need a propper dns entry.
Here's what I can see from the outside:
http requests to btshadows.net port 80 time out.
http requests to www.btshadows.net port 80 get redirected to 188.8.131.52 (redirectf.dnsix.com)
dig'ing for btshadows.net returns two results: One in the 66.X netblock and one in 68.X
Same goes for www.btshadows.net (same IP adresses).
Could this be a firewall issue? I can PM you the full IP addys if that helps, though everybody can easily find out for themselves
