Site/forum works fine but cant connect to wiki?

Maybe some1 could help me out, i just cant connect to wiki here, connection timed out, tried google dns/opendns, :/... cant even ping 160.153.137.153.

Wiki was sometimes unavailable for me as well, but only temporary. Maybe hosted elsewhere.

The main page (incl. forum) is using a domain and hoster located in Germany.
The wiki is separated by domain and also using a hoster based in the states.

So it is absolutely possible that you can reach the main page but not the wiki - or vice versa.
Depending on your own location and ISP there might be day times and used internet hubs your ISP is struggling routing you through.

Using the tracert command you may find be able to find which internet hub is causing the issue. However since this is out of your reach to change something, the only way you can try is to use a VPN (specifically one that is focused on gaming) as a VPN does change your routes through the WWW.
