There was probably about a 2 minute window where anything that was posted was lost. So a couple of posts in the FA section (not my posts, replies) may have been lost.
What I did, I tried to prune the forum. I had it to remove any posts that haven't had replies in the last 30 days. Cut the post total from 9000 to near 3000. Problem was, critical threads like the calendar posts haven't had replies since they were put up (only edits)
