I think I might say how I got lucky with it from my personal View.

During the last Minutes my Friends and I kind of spammed the Server Button (for me it was just once within a minute) and once it was up it also took a bit till the Log In Button but came within a few Seconds.
Now comes to the Login Queue Part: Even if we all logged in at like the same time only one friend and I got happy with just a 100 queue. The others already got up to 1000. That was purely Luck actually. I can tell that I am european playing on a North American Server. So my Connection is not the best. Therefore I can say that this was mainly pure Luck.
