This might be not a proper Minecraft bug, but i might can get help here.

The situation is the following: I can play every game properly with a stable ~30ms ping, except for Minecraft. No matters on what server i'm playing i have always a 80ms+ up to 3000ms ping, even to the servers are located in my own country. As i said every other game runs very fine pingwise which also have servers located in my own country. Every version i use is "affected".

Any tips please?
