I believe you are talking about the site previously discussed in these threads:
This thread would imply you have recovered (to a degree, at least) and that then suddenly on 5th you lost the traffic?
I am wondering if you can provide some timeframes between finishing rebuilding the site and the disappearance of your traffic. Perhaps some numbers of drop on 5th may be helpful to members?
Have you in a meantime been doing link juice recovery as mentioned in the second thread above?
