Suggestion. Use a ping plot program, or you can run in window command line (if you are savvy enough, below is the command to plot to the login server). I personally use the below linked software to ping plot. See if Destination address is reachable. If it isn't try a free VPN, like VPNbook and run it through a European VPN.

Once in cmd, type "tracert login.nostalrius.org" and see if it times out (like shown in the image, went 30 hops and not reachable) or completes the loop. If it doesn't complete the loop, use a VPN to login. A few of the nodes routing to the server have been giving issues, so best to use a VPN until you get a clean ping plot (traceroute).
