Holy crap I was looking for others who had this problem! Mine started relatively recently as well. I have Fios in Pittsburgh, PA. From launch until late Sept, no lag at all, suddenly I get these random packet losses. Opened task manager > Resource Manager, and watched the network activity for FFXIV, as suspected it will randomly stop all network activity for a few seconds and either rubberband me back in or I get the 90k error Glad to see I'm not alone, maybe this will be addressed.
