The DOJ requested records including the IP addresses of everyone who visited the Indymedia.us Web site that day last year. All sites generate such records (server log files), although each site owner sets their own policy for how long to store server logs before deleting them. Privacy advocates encourage the practice of erasing logs as soon as possible. It helps shield their customers, and Web site owners can avoid being bothered by requests from the authorities. Indeed, in this case Indymedia could not provide the Government with any IP address data as it had been purged after a few weeks.
Other Web sites beside Indymedia.us may preserve the history of visitors and their IP addresses for months or even years. If you have any concerns for the privacy of your surfing tastes, consider using an anonymous proxy server to keep your address out of their logs.
