This is the latest update from the sys admin team:
"Hi everyone, we are still working on our sync backends. In our tests we have not been able to get the performance up to where it needs to be at. We are doing a lot of maintenance that will take more time. We are so sorry how long this is taking but we are working night and day to get things back into shape. We really appreciate your continued patience while we work on getting Sync back up. Yours, the Sysadmin Team."
