@Can Someone Pause Update Distribution Until Servers Are Working Properly?

Alos in general the slow download server should not cause problems with the updates that break instances. The update will not just be completed and the instance will only have one more downloaded file in the updater download folder but stay stable and running

This is obviously not the case. The upgrade fails and leaves things in a broken state. You cannot simply just remove the .state file to get things back either. You have to restore from backups.
