Their traffic seems fine right now, I can trade smoothly, place buy and sell orders of NXT several times and it worked as how it used to be, so I figure they're cleared their issue. And about your ticket, maybe it's a stupid suggestion, but since they close them all, why don't you open a mew one? Maybe they intentionally close every ticket to "reset" the ticket submissions that became chaotic and we are supposed to submit a new one?
