We did alot of testing with this.
My connection was fine until the friend from the US joins us.
If he left my connection returned to normal
If he rejoined us it would degrade again.
repeated about 10 times always same result in the end.
My internet connection is 75MB down 20MB up fiber optic to the box.
The server we where on is in the UK
But this happens on other servers as well.
My ping to UK servers is between 10 and 30
It feels as though the slower connection is affecting the higher speed connection.
Once they are in the bubble.
THIS WASNT A PROBLEM BEFORE THE LATEST UPDATE.
