FYI, The server will be offline the next couple days. There is a network issue that needs to be fixed locally. I will try to get to it by the end of the week. The physical hardware isn't in my possession at the moment so its not a quick fix unfortunately.
So there was an issue with the DNS server. When I was testing before I was still connected through VPN so it worked fine for me. The port 53 udp packets were being dropped. It should be fixed now.
That's normal. I have ICMP packets being dropped intentionally so it's not going to respond to ping requests. If you need to check whether the server is online just check the top of this page app.php/page/servers . That image at the top will turn red and say "Server is Offline" if it goes down.
