The recent update, geared at improving site stability, triggered a problem wherein our gameservers began to overload our storage servers. I’ve since throttled that back and subsequent restarts no longer do this, however the effect of this problem caused game load failures, which triggered our migration code designed to allow us to smoothly transition from the old storage platform to the new one. This has caused a recurrence of the bug that we saw 3 days ago where a number of correspondence game 3 days ago timed out because of a very different storage system failure. Unfortunately, in first case I was able to restore games to their state because the data was simply not accessible during the time of the migration, however in this case, the old data was re-migrated and overwrote the current data, and I will not be able to recover the lost moves.
This is a terrible failure on my part, and I apologize profusely. I’ll be working through the night to accelerate the migration so we can get rid of the problematic migration code once and for all.
