Dark Web Map: Introduction
The Dark Web Map is a visualization of 6,608 sites that were present on the dark web during a January 2018 crawl. This is not an exhaustive listing of all onion services, because many onion services are not easy to discover by crawling. Also, you may recall from the previous section that not all onion services are websites.
According to the Tor Project’s statistics, there are over 60,000 onion services running at the time of publication, so our sample represents about 10%.
