From Tech Support:
Update at 9:15 PM EST on December 23rd 2016
The switch to the new servers have gone well. Most servers are up, and running super fast. No problems have been reported with posting, or slowness.
Our team is still sorting out some things, however.
C7 and C12 are currently under maintenance. The goal of this maintenance is to retrieve the recent posts that were lost. The process is expected to take several hours.
Some profiles have missing skins, friends, messages, etc.. All of those profiles are on the same server and it is being worked on. Everything should return to normal.
Once C12, C7, and the profile server are in good shape, the mail script will be reinstated and notifications will start going through.
For any issues, please feel free to post here, or email firstname.lastname@example.org
Please allow extra time to support emails, due to volume.
Joanie and I both asked about the awol profiles but Chris has also noted that things are being worked on, some re-imports have to be done and it can take hours.
The Switching over thread is already large and takes time to read through, sort out what has been answered and what is needed for here.
Chris is swamped with the support emails, main support board and having to liaison with the tech team. Even if your profile isn't working, you should be able to get to the yuku support board and read what's there.
For anyone who can't, I'll keep trying to pull the info and post it in here.
