My winterbash on top navigation is not found at all. Already Ctrl + Shift + R, Ctrl + R, and restarting my chrome.
I noticed that since yesterday winterba.sh is blocked by the proxy my company uses. In my case it is Bluecoat, which blocks winterba.sh as category "Gaming".
That could be the issue on your side, too. To determine whether that is the case try to open http://winterba.sh directly.
