For the past week after some magical updates from Spiral Knights, I've been playing in every game session with 1-bar connection rather than 2-bars and was having unpleasant experiences from collision hit errors from monsters to sudden spawns of monsters and projectiles (from the result of mysterious connection choke that lasted half to one second.) I thought my campus wi-fi got worse, so I did further digging using Resource Monitor from Windows.

When I entered a game session, I looked up the current server's IP address and realized that the game incorrectly placed me in US Amazon servers (*.compute-1.amazonaws.com; United States), despite that my IP address is actually is from the south-west Asia region.

After this discovery, I went into options and changed the region from "From IP" to "Europe" and launched another game session. Now I'm in the correct Amazon servers from Europe (*.eu-west-1.compute.amazonaws.com; Western Europe) and I gained a more stable connection in the game with 2-bars.

So now I can't always trust the "From IP" region in the game options. If you notice a degraded network connection from the Spiral Knights server for the past week, try changing your region to "USA" or "Europe." You might gain a bar and better game experiences on the next session.

That is all.
