Why does error 3102 take so long?

I dced and it's almost been 10 minutes. Why is it taking so long?

Why is there so many 90002 errors that get every 5 to 10 minutes. Only way to not get 3102 error is to completely exit ffxiv then login again. Otherwise get them for 5 to 10 minutes.

I could be completely wrong, but I think it was explained to me that you when you have a 3102 disconnect, your ISP is actually still sending a signal to the game server. A 'cached' connection. So even if you aren't in the game, as long as the program is still running, your ISP is trying to keep you connected automatically. Thus shutting the game down and relaunching gets you back in quicker in most cases because it will force your character out of the game.
