Hi, playing from the south of France I also have issues...
Quite a good ping (68ms) but changing zone can take minutes, and also when switching character. When logging out a character it can take between a few seconds and 2-3 minutes to get back to the character selection screen, and when logging another character it can also take randomly from 5-10 seconds up to a few minutes to load.
Loading "litigious areas" is also very random (from long time to kick-out).
I hope you'll find the solution soon !
Thanks
