Since the June 4th patch, Southsun on Yak’s bend server has been extremely laggy and disconnects like crazy. For me personally the disconnect codes I have been getting are the following
1022:5:1:872:101
7:11:3:191:101
The lag has been extreme at times and comes during big events, small events, overflow, no overflow, simply just always there. It is happening with most of my guildies which are spread out from east to west coast U.S. and Canada, so no particular area or ISP.
Before June 4th patch I had no issues, and have no issues in any other zone. Even huge WvW fights don’t have anywhere near the lag that is Southsun right now. Map chat seems to suggest many people having the lag and disconnect issues
