It looks like the site maintenance is complete and from my perspective the DNS changes have gone through.
If you go to the homepage and see a message called “Site Maintenance” in the “Site News” section, it means you are being directed to the new server. If you don’t see that it means you are still being directed to the old server and you won’t be able to read this.
I guess it will take a few hours for the DNS changes to propagate. Last time I moved the site it took a couple of days to complete for everyone.
