I have a heavy lag after the last update

1

Before the last update,my ping was 230,and had not  the packet loss.But after the last update,my ping raised to 370,and always have the heavy packet loss.

my friends and I have this problem.Now I live in Japan,and my friends live in Italy.I think a part of Chiese player also have this problem.

This is a bug of the server？

 

  thanks
