This is a collection of Geocities data downloaded by a bunch of people who call themselves ARCHIVE TEAM, who began scraping the Yahoo! Geocities site during a six month period in 2009, before Yahoo! shut down geocities.com on October 26th, 2009.
At the time of the purchase, Geocities was the THIRD most popular website on the Internet. Even by the time of its shutdown, it was in the top 250. We don’t have complete rock-solid knowledge of why it was shut down, but all signs point to Yahoo! trying to get back to basics (like, uh, having a huge audience?) and Geocities magically didn’t fall into this new "focus", and lacked any internal cheerleader to make it last through meetings.
Yahoo! succeeded in destroying the most amount of history in the shortest amount of time, certainly on purpose, in known memory. Millions of files, user accounts, all gone.
