There shouldn’t have been any service outages that affected the TC session at 10 AM today. Can you provide a log file from that session? We would need to correlate it with our Team Create server logs & see what went wrong.
For the Sunday / Monday loss, that is somewhat expected in the sense that we had a large service outage during that time, but this should have triggered a disconnect in Team Create that prompted the builders to save their work. It would also be helpful if we could get log files from those sessions to check the Team Create server logs there as well.
As for the Drafts issue, drafts are entirely local and should not be affected by any service problems. They are backed up to the local disk every time you make a change, so it is interesting that even still hours of work were lost. Can you provide the log file from that session as well so we can check what went wrong on the TC server & your Studio client?
