I am having this problem too. I just started last week but I have been getting disconnects (mostly 90002) since I started. I posted in the sticky but got no response. It happens randomly, anywhere at anytime. I have been getting disconnected during both battle and crafting causing me to die/fail and costing me 1000's of Gil in travel and high quality ingredients. The game is pretty much unplayable at this point. I don't know why I would buy a subscription to a game I can't even play. (Which is a shame because from what I have seen so far it's quite a good game.)
