As is typical, we log http requests to our server. This means that we know the originating IP (e.g. 18.104.22.168) address of a user agent requesting a URL. We also know the Referer and User-Agent information accompanied with an HTTP request. We do not log the specific identity of visitors. We occasionally analyze the log files to determine which files are most requested and the previous site or user agent which prompted the request. Our logging is passive; we do not use technologies such as cookies to maintain any information on users.
We also log requests to our search, cgi, and list maintenance services. This data is only used for administration and researching the efficacy of our tools.
Logged information is kept indefinitely as administrative and research material; it is not disclosed outside of host site personnel. Aggregate (completely non-identifying) statistics generated from these logs may be reported as part of research results.
