well normally I can access it without any proxy server, my IP address without proxy server enabled is 201.172.234.185
But when I have problems to access the site which are very rare, in the internet options in the conexions tab on the Lan Configuration I enable this proxy server address: 165.228.133.10 and the access port for it is 3128
when I have that enabled that which is by ticking the mark that says use a proxy server for Lan, the site works, but if I disable to use my connection default settings the site just shows a page not found error, at first it looks like if it is trying to solve it but then after a bit it only shows the page not found error, as I said still monday and tuesday it was working normally without have to enable the proxy server
Edit: what do you know? just a IP address change and it worked, though oddly enough the new IP address is still on the same range the new one I got is 201.172.234.100
Kinda odd if you ask me but at least it is working now
Also and as an interesting thing, I tried to access to Nexcess and I got exactly the same error I'm getting with this site, page not found, I noticed that both sites are inside of the same starting rank of IP address which are 208.69, the only thing that changes are the last two sets of numbers, for Adultfanfiction net is 208.69.121.85, while for nexcess.net is 208.69.120.5
maybe the server has my rank of IP address blocked or something, is pretty odd since it tries to open the site, the progress bar on the status bar on the browser advances 3 lines slowly and then it puts the page not found error.
