I've recently come into some hassle with my dedicated server. I've done as much debugging as I can myself, from running tracerts and pings with a script. Watching the throughput of the server, its appropriate for its utilization, roughly 20mb/s in/out. The issue is, sometimes the server appears to become unresponsive to the outside network, however, it itself stays online and functionally connected. This causes all my clients to drop connection from the various services I host for about 2 minutes, sometimes longer. It appears as a major drop in packets, however I am unsure where in the routing something may be incorrect. Attached is some diagnostic information
