Suspicious login after realm crash

Greetings. I would like a staff member to answer this, if I'm not asking too much.

Icercrown just crashed @ 10 minutes ago (@18:30 Server Time), and all of my accounts that were online at the time appear to be logged in from US. I have a total of 3 accounts, 2 were online at the time of the crash and both appear logged in from the US. However, the third one was not online at the time of the crash and the last login location is fine.

This happened to most of the people who were online at the time. Only Icecrown seems to be affected, though, as I asked the Lordaeron branch of our guild and nothing happened there.

Please, any staff member, give us some words on this because my guild and I are worried.

When you connect to logon server but don't log on a realm it shows logon servers IP instead of your IP and it's in US.

I did not. The realm crashed, I went on Lordaeron for the time and in the next 10 minutes it was back up and people were talking about this US thing. I didn't log in at all, we used teamspeak to communicate.

When realm crashes people try to log back in but they can not log on the realm so they are stuck in realm selection screen. While they are there it will show US.
