I’ve tested this a few times in the past half hour. For me at least if I try to connect to a WvW borderlands after today’s update the game remains stuck in the loading screen until I either quit or eventually lose connection. Afterwards I can log into character selection screen and then it loads for a few minutes and states I’ve lost connection. After about another 10-15 minutes I’m able to log in. If I try to connect to a WvW borderland the scenario repeats.
