what did you mean about the date, by the way?
The corrupted ito file has been updated on 2012-08-07

And the iceberg thread already mentionned this date...

I tried to ask calcium_chan about this iceberg, where all those informations came from but I had no answer...
I'm digging the newspapers to see if something related to our case happened during that day in france , usa and canada, but I didn't find anything usefull yet.
