Patience, it depends when & from where you're logging in.
There are typical busy hours of the day as much as low-down times.
Being in EST-Zone here (NY, Quebec, etc)... i found out that once California+ gets home for dinner and some of their usual early evenings PC stuff - there's a sharp peek in servers call.
You may get lucky on weekends but it's already past-midnight here and i doubt players all over the globe live full 24 hours without any sleep.
