 > What do you count as a failed download? Does your downloader cut off the
 attempt after 50 or 80 seconds or something? Do we have any sense of
 whether these failed downloads got 0 bytes or 'most of the bytes' before
 failing?

 The downloaders do not "give up" unless the socks connection is closed by
 the other end. Although, I now realize that its probably smart to have the
 client "give up" so as to avoid knocking it out of the simulation because
 its download hung. Doesn't Tor kill the AP connection if it can't get a
 circuit by a deadline?

 I do not explicitly count failed downloads, but I do track bytes received
 over time. So we could count partial downloads that never completed, and
 infer failed downloads as partials that were started before the last X
 minutes of the simulation (to avoid counting legitimate in-progress
 downloads as failed).

 > the clear next experiment: run the n23 side with "N3Initial 50".

 Its running now:)
