For 2 or 3 days I have experienced several R0s and full disconnects (different POL messages). Additionally, I have received a message about network congestion when trying to get items out of delivery box (today) and searches have failed using /sea and auction house listing. It hasn't happened constantly, but it happened sporadically at various times of day. A few times ISP has gone down, but most of it was been on FFXI server side. Also, two instances of Windower freezing as well.
