UPDATE -- Friday 3pm
Network changes will happen at 11pm Pacific Time.
The main difference between this happening tonight versus last night is that the site will not be down for maintenance. The window of time for the site being down will not be nearly as long as normal maintenance nights. At 11pm we will begin the updates. The site will be down for approximately 30 minutes.
See my above posts for more info on what you can do if after midnight you're still viewing the page that says "Auctiva has changed DNS".
