Internet Archives Blog: “Today we updated the Wayback Machine with much more data and some code improvements. Now we cover from late 1996 to December 9, 2012 so you can surf the web as it was up until a month ago. Also, we have gone from having 150,000,000,000 URLs to having 240,000,000,000 URLs, a total of about 5 petabytes of data. (Want a humorous description of a petabyte? start at 28:55) This database is queried over 1,000 times a second by over 500,000 people a day helping make archive.org the 250th most popular website.”
