I got no packet loss on the crack server, so it got to be some kind of routing issue there. Nothing I could do. Since when does that happen? Maybe a MTR / WinMTR result could help identify the hop that causes the loss. Looks like 213.248.89.93 (hbg-b1-link.telia.net) is causing trouble but that's nothing related to the server. The "loss" you can see at gw02.contabo.net is intentional, our hoster got some hardware configured to not respond to pings, I don't know why.
Btw: You can use the domain crack-gaming.de to not have to copy the IP from the serverbrowser / wherever you got it from.
