When you know you are about to LD/Crash due to connection error, press either ALT+F4 or better yet, kill your game process, then run the launcher and log in again ASAP, you probably will find yourself in a very short queue (the queue of people who got DC'd).
If you let the client go to server selection you will end in the big 2500 person queue (Well that's what it is on TOFN server usually) and resulting in the "I was in game and got connection error 9000" frustration.
You can usually tell that you are about to LD when you no longer can use your skills actively, or your guild shouts on TS "Your char went offline !!!oneone OMG" (then it is sometimes too late )
