A service that allows Google's search engine to be used anonymously is running again after a code change briefly knocked it down.

Scroogle allows people to use Google's search engine without the company recording their search terms with their real IP (Internet protocol) address. Google's search results are proxied through a Scroogle server and only sees Scroogle's IP address.

Privacy activists contend that connecting IP addresses with search queries -- done by all major search engine companies -- poses privacy and security concerns. Google anonymizes the last octet of the IP address after nine months, but many argue that level of anonymization doesn't go far enough.
