hmm... I shot straight in a little while ago. Was tooling around a bit, logged out/in again testing before posting in the thread about lobby server issues. Zoned twice now (running down allied hunt list targets) with no unusual lag or anything.

Maybe there's something going on with specific lobbies? Can check it via netstat or resmon to see which IP you are connecting to when sitting at the character select screen.

These are the registered IP's for the three CA lobby's (I use neolobby02):

neolobby02.ffxiv.com (199.91.189.74)
neolobby04.ffxiv.com (199.91.189.93)
neolobby06.ffxiv.com (199.91.189.106)
