I always see that it is a new server, but, :
1. i post and post, since there is notice that it's okay.
2. it always appears that it is an old server.
3. what I did is to refresh it.
Can you fix the problem?
So ... after you post you see the old server?
The internet must know where to send you, so they have lists of where websites are. When I move servers an announcement is sent out saying the new location, but the update takes many hours or days to get to all corners of the internet, and so sometimes you may be getting directed by an older list (my best guess of what may be the cause)
