The crawl was very shallow, and aimed at gathering a large number of hosts, but a small number of pages from each host. Note that before April 2006 the URL order was not exactly lexicographical due to some locale issues (the graph was anyway correct). The current dataset has been correctly permuted so that URLs are ordered lexicographically.
