Getting DC'd from another location (hoping to get an answer from staff)

I tried logging on an alt account about 5 minutes before this happened. There was at least 1600+ players in queue at that moment (and this very moment). Then, my main account got disconnected. I didn't think anything, until I logged back on, and got immediately dc'd again. Surprisingly, my alt account didn't dc, so I tried again. Several times my main account got dc'd immediately after I log on. So I went on the website, hoping I didn't get hacked (yes I have 2-step enabled). And I see I was logged on 1 minute ago from Germany, which I'm from the US. I asked my guild mates on voice chat, 4/5 got dc'd also, all 4 of them I asked to check their accounts and ALL 4 of them were logged on 1 minute ago from Germany also. I checked a /who at that point on my alt account and there was now only 9000+ players online. I know there was a topic about this somewhere, but nothing came out of it. And it appears this happened only after the 'upgrade' a couple of weeks ago. So, what's going on here?

I had the same problem several times, after few attempts of restarting network (and home router), everything worked fine.
I am from Croatia, it reported I logged in from United States....
