I had a answer to this question on boardgames.se (private beta) that I took several hours to compose (it was fairly long and comprehensive, and I had to go grab dinner in the middle of composing it). When I finished it, it posted just fine, though it may have already been in the middle of the data center move; I'm not sure. The answer showed up on the static site during the data center move, but then after the site went live again, it was gone. The answer URL was this (extracted from my browser cache), but that points just to the question now, my answer is missing.
I have managed to recover the answer from my browser cache, and run that through an HTML to Markdown converter, so I can re-post it. However, I'm wondering if there is some part of the migration that is not yet complete that is intended to pick up this missed content. I'm pretty sure there was also a comment that I made which is now missing (which is less important than the answer), and given that I experienced this I would be surprised if no one else did.
I asked about this on the datacenter move thread, but I haven't heard anything about it there (someone hypothesized that there might be another pass of moving data over, but that was 9 hours ago and it hasn't reappeared yet), so I want to see if anyone here has any insight. Is the move done completely now, or is it still in progress? Will any of this lost content be retrieved, or do I need to dig what I can out of my caches and repost it?
