Just to speculate, but it is possible that you may have been more attentive than me at noticing that outage, and everyone may have experienced the same loss.  It may be impossible to audit the transaction history to resolve the issue to any satisfaction.  Since this would have been from a single user during that time since they would have been unable to create a new order, you could request it from the user to use the withdraw function to send the delta amount to your deposit address on good faith.  It is possible that they may have also noticed the discrepancy upon the wallet's return at that time, and chosen not to say anything for obvious reasons considering it is in their favor.  You may be able to find total or partial resolution that way.  To put an optimist spin on a possible reality, it may not be possible to definitively audit the history for this to be resolved administratively or otherwise.  As the technology is utilized it acts as a continuous test of the longevity of the self-sustainability of the initial vision used to determine provisioning.  It demonstrates the growth and depth the entity itself has reached, and while in this case it needed some finesse to compel the required stability, that solution had to come from somewhere, and the loss of that disproportionate sum is what provoked the resolution the benefits of which we have enjoyed recently.  CohibAA, you are correct in your considerations, and I can understand your resolve on this issue, but I think everone's options for resolution for this issue were limited at best from the onset, and was likely the reason for the nature of the cumulative response.  We are proverbially all in the same boat, and while we could head back to port because of a torn net, I think it has now been mended and while the fishing that was lost during that time may not be able to be recovered, in general the nets hold fine and the fishing is good.  To touch on your second question of if IRC chats are logged and reviewed, I know they are logged when they are in the channel, but they are likely not reviewed in detail, especially when there are large numbers of user events, but I speak only from my personal habits to that effect. 

Hope this response helps, and good luck in your pursuit.
