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.

Audit: FEMA must do better tracking its contracts
By EILEEN SULLIVAN – 16 hours ago
WASHINGTON (AP) — The Federal Emergency Management Agency failed to follow some federal contracting rules, making it impossible to know whether the agency got its money's worth during disasters, a government audit found.
In a report released Tuesday, the inspector general for the Homeland Security Department said that auditors looked at 32 disaster contracts from 2007. That year, the president declared 65 major disasters, and FEMA spent $1.5 billion on disaster contracts, including purchasing and delivering ice for hurricane victims.
FEMA was unable to find copies of some contracts. In other cases, information on the contracts was incomplete. None of the contracts were in electronic form, and some contracting officials kept the contracts on their desks or filing cabinets, the report said.
FEMA's contract management opens the door to potential waste, fraud and abuse, the auditors said.
FEMA currently is setting up a room in Washington to hold contracts, and 80 percent of the contracts are there. FEMA told the auditors that the agency also is working to resolve many of its contracting problems, according to the report.
The Government Accountability Office, Congress' watchdog, has reported that all homeland security agencies have had challenges managing contracts since the department was created in 2003.
FEMA has been criticized for contract mismanagement and abuse during 2005's Hurricane Katrina. A 2007 report by House Democrats found that the government awarded 70 percent of its contracts for Katrina work without full competition, wasting hundreds of millions of taxpayer dollars in the process.
"FEMA's contracting system has long been plagued by inefficiencies that hamper service delivery to disaster victims and waste taxpayer money," said Rep. Bennie Thompson, D-Miss., chairman of the House Committee on Homeland Security. "As FEMA's new leadership takes charge, they must resolve the problems created by the previous administration."
