Over the past couple of weeks I've experienced some vast issues remaining logged in.

(and now it happened again, just as I was creating this post..)

"An Error has occured on the game server.
(30002)1319625471,24178548,5"
several times a day. Temporarily kills my connection to the FFXIV game server and the forums.

Not so fun as it has a tendency to happen just as I start making expensive synths or begin a leve.
