Dear list members,

The next big data review regarding the "Trying Trusted Tor Traceroutes" project was initiated this week. It will probably take a while (weeks) before we have solid conclusions.

We are very close to 100 complete runs from different IP's, in fact 99 right now. I hope that we will reach this goal very soon :-)

We are not sure yet if we gathered enough data, but time will tell. We want to thank you for your support and if you want to make sure that we have more data in case the amount we collected turns out to be insufficient, then join us or keep running multiple rounds.

Project:

http://web.engr.illinois.edu/~das17/tor-traceroute_v1.html

Results:

http://datarepo.cs.illinois.edu/relay_scoreboard.html

I make sure that this list is getting the results from the data review before anyone else.

Decided to run it on another 3 servers today, at different data centres. All show similar to below. (summary: https not working to retrieve archive).

Hi,

Do you still have this error occurring ? Checked the download, should be working.
