FYI on btc-e the volume showed approx 10k transacted at the time.
Don't expect to hear anything soon from BTC-e - they are not exactly forthcoming with information. And I would not trust their explanation anyway unless it was accompanied by a reversal of trades/compensaton for losses, and that ain't gonna happen. Words are cheap ...
then it was quite profitable for the investor
By the way there is a message on their official twitter that they are handling with some network issues in the data centre.
