We have a player playing in early hours in EU, and he has had that issues for a few days aswell. So the time frame is why normal EU players dont have to deal at the moment with the issue.
Thats a known problem that appears from year to year. The only thing you can do is waiting for the problem to dissappear.
I think we once couldnt join servers for almost a week some years ago (except for the killbox server, weird^^)
