Bonus: Why Is My Ping Higher After Changing Server In MW3

1. Distance: If the new server you joined is located farther away from your location than the previous server, the increased distance could be causing a higher ping. This is because data has to travel a longer distance to reach the server and return to your computer.

2. Network congestion: If the new server you joined is experiencing high traffic, your ping may be higher due to network congestion. This can happen if many players are connected to the server or if there is an issue with the server's network infrastructure.

3. Server performance: If the new server you joined is experiencing performance issues or is not optimized for the game, your ping may be higher. This can cause delays in the server's response to your computer's requests.

4. Internet connection: Your ping may be higher if there is an issue with your internet connection. This can be due to network congestion, interference, or a problem with your router or modem.
