Web wide crawl with initial seedlist and crawler configuration from March 2011. This uses the new HQ software for distributed crawling by Kenji Nagahashi.
What�s in the data set:
Crawl start date: 09 March, 2011
Crawl end date: 23 December, 2011
Number of captures: 2,713,676,341
Number of unique URLs: 2,273,840,159
Number of hosts: 29,032,069
The seed list for this crawl was a list of Alexa�s top 1 million web sites, retrieved close to the crawl start date. We used Heritrix (3.1.1-SNAPSHOT) crawler software and respected robots.txt directives. The scope of the crawl was not limited except for a few manually excluded sites.
However this was a somewhat experimental crawl for us, as we were using newly minted software to feed URLs to the crawlers, and we know there were some operational issues with it. For example, in many cases we may not have crawled all of the embedded and linked objects in a page since the URLs for these resources were added into queues that quickly grew bigger than the intended size of the crawl (and therefore we never got to them). We also included repeated crawls of some Argentinian government sites, so looking at results by country will be somewhat skewed.
We have made many changes to how we do these wide crawls since this particular example, but we wanted to make the data available �warts and all� for people to experiment with. We have also done some further analysis of the content.
If you would like access to this set of crawl data, please contact us at info at archive dot org and let us know who you are and what you�re hoping to do with it. We may not be able to say �yes� to all requests, since we�re just figuring out whether this is a good idea, but everyone will be considered.

Oh, they try hard to make it look all tough and streetwise, but really it's all "warmth and humor". Drenched with it, apparently.
A dark-skinned Puerto Rican hung up like LAUNDRY, get it? Such a genius metaphor!
I like the ambiguity in "attempted killer" -- "well, maybe he was tryin' to murder the guy and maybe it was self-defense...I'll never tell!"
it's all "warmth and humor". Drenched with it, apparently.
But starkly drenched.
"Joey, Joey Doyle!...Hey, I got one of your birds. I recognize him by the band...He flew into my coop. You want him?"
The cover makes it look like "The savage power of MANCHILD IN THE PROMISED LAND DOWN THESE MEAN STREETS" which not only makes no sense, but is super-long. And just what the hell is the "MANCHILD IN THE PROMISED LAND" about? Is it a tagline? Did they leave off the "a" that would have made it make some sort of sense? Is Piri's nickname "Manchild"?
That NYT blurb makes it sound like this book gives you a massive of case of heartburn/indigestion. Get out the Pepto! Also, thanks, Piri, but I don't think I want you to make me live in hell with you; I hear it's awfully crowded and hot this time of year.
That is one of the most dramatic back covers I've ever read.
