In January 2014, documents provided by Edward Snowden showed that a Canadian spy agency was using a unique identifier to track thousands of Canadians as they moved around the country. All of the tracking originated from an unnamed airport.
So we got to thinking: how hard would it be to replicate this little experiment? Could we use our own online identifier as a way to track our own movements through time and space? The answer, perhaps unsurprisingly, is: yes. It's easy to do, and it reveals what we do, when we do it, and where we go.
Like many other websites, Ars Technica uses a voluntary user login system. These logins allow you to do things like leave comments at the bottom of each story and participate in user forums. Each time you log in to Ars, we will record the date, time, and IP address that you logged in from. This is common practice: almost every website keeps similar records. However, Ars typically keeps only one record per user with the last date, time, and IP address used. We do not keep any historical logs of login data.
