The current production instance of http://kdm-manager.com is going into maintenance mode in about 15 minutes.
The maintenance message will appear until the migration is complete and the DNS update(s) have had time to propagate: it could take anywhere from a few minutes to a few hours.
Thanks for your patience and see you on the other side!
Update: as of Sun Sep 4 18:16:14 EDT 2016 we are officially in maintenance mode.
Update: as of Sun Sep 4 18:51:28 EDT 2016, we're done and the migration is complete. DNS may still take some time, but it has already propagated to Google public DNS (probably because I'm doing DNS through Google now).
