A few more thoughts: * You probably don't need the full URLs of the content being accessed, so those could be anonymized and replaced with random identifiers to some degree, right?
* Someone might be able to monitor the user's end of the transactions, such as by having university network logs that show destination domains and timestamps, in such a way that they could pair the university logs with Wikimedia access traces of one second granularity and thus defeat some measures of privacy for the university's Wikimedia users, correct? * I am not sure that the staff time required to analyze this request and produce the data is a good use of resources on Wikimedia's end. Toby would be a good person to ask about this. Pine On Sep 20, 2014 12:45 AM, "Pine W" <wiki.p...@gmail.com> wrote: > Thanks for the explanation.
