Apparently the JP Duty Finder service has crashed and there will soon be a 2 hour maintenance to fix it.
I got kicked from a duty when it crashed. I came to the forums. I looked around for some recognition of the problem. 30 minutes later, I was still looking around. Eventually I heard about the maintenance through the grapevine on my server.
After hearing the news, I came back to the forums and looked some more for details. As usual, no info about it. At least not in English on the English forums. Info about every NA/EU technical issue as it came up, but nothing about JP servers.
Dear SE, you have NA/EU players who have been stuck on JP servers since beta due to your service issues. We deserve updates too. Please start addressing us the way you do everyone else. Kthx.
