With everything running on UDP, i lose access to all of my usual tools to analyze network issues with a service. I was noticing constant "server is not responding" messages when I was first trying to play. they cleared up after a while on their own and it is working okay now. But during the issue I was blind.
Network speed was good, port was open and being forwarded properly.
The logs don't show any problems.

How can I get more information on what is happening to my client/server communication without access to things like telnet, tcp packet ordering/numbering, etc?
For the Devs - Very interesting use of UDP to create a resilient connection, any chance you can build in some network diagnostic tools to the server to help identify problems? Anything coded specifically for Factorio will be better than a third-party tool.
