My longtime friend Zack Weinberg ([personal profile] zwol) needs help in his research to measure Internet censorship. He's a grad student at Carnegie Mellon University, an sf fan, and a longtime open source software hacker.

The short version is: go to https://research.owlfolio.org/active-geo/ and hit the Start button on the map.

More details:

Zack's doing experiments in "active geolocation", which is when you try to figure out where a computer physically is by measuring how long it takes a packet of information to go round-trip between one computer and other computers in known locations. This has been studied carefully within Europe and the continental USA, but much less so elsewhere.

More specifically, Zack is trying to develop a technique for verifying that VPN exits are in the country that their operator claims they are. His larger research focuses on measuring Internet censorship, for which he needs network vantage points in precisely the countries where it's hardest to get reliable server hosting. He could go with the commercial virtual private network (or VPN) providers who say "sure, I have a host in Malaysia/Ukraine/Iran/etc. you can choose to use," but how can Zack know that they're telling the truth? Commercial VPN operators may prefer to locate their hosts in countries where it's easier to do business, and only label them as being in harder-to-access countries.

So Zack is looking for volunteers who can visit that page, which will run measurement scripts, on computers physically located all over the world. South America, sub-Saharan Africa, South and Southeast Asia, and Oceania locations are especially helpful, but he can use data from anywhere.

Once you click "Start" on the map at https://research.owlfolio.org/active-geo/, the page will run a test/demo to see whether you could help. If you can, then you'll see the consent form below to ask for more information about your location and you'll see the CMU’s Office of Research Integrity and Compliance notice.

Here's more about the research questions he is investigating, here's how to help using a command-line tool in case you'd like to give him data from a computer that you only have remote shell access to, and

In case you want to spread the word about this request, here's a public tweet you can retweet:

I'm looking for volunteers to help with a research project: https://research.owlfolio.org/active-geo/ Especially want people outside Europe and North America.


And you can ask [personal profile] zwol for more info if you have any questions.

Thanks!
