Question

Identify the specific 2008 web data collection donated by the organization that began contributing crawl data to the Internet Archive in 1996. According to the archive's records for this specific 2008 collection, what is its current public accessibility status, and what general temporal condition is applied to this donor's daily data flows before they appear in the Wayback Machine?

Answer length: 200-300 words.

Show hidden checklists

Depth checklist

Target Entity: Alexa Internet (Donor) / Alexa Web 2008 (Collection)
Logic Proof: The agent correctly identified the donor based on the 'started donating in 1996' fact and located the specific 2008 collection details.

Width checklist

Target Collection Name: Alexa Web 2008 (Crawl data)
Accessibility Status: Currently not publicly accessible
General Condition: Data is added after an embargo period

Examiner rationale

The question utilizes Deep reasoning by masking the donor (Alexa Internet) behind its historical relationship with the Archive (starting in 1996). It requires Wide aggregation to retrieve the specific status of the 2008 collection (not public) and the general policy for daily data (embargo period). Note: The provided source text was unrelated to the 'History of swimwear' domain; the question adheres strictly to the provided text to satisfy the 'Absolute Grounding' rule.

Judgment

Better

NONE

Score 1 - 0

Both agents correctly identified the donor (Alexa Internet) and the general facts regarding the embargo (6 months) and accessibility (dark/unavailable). However, Agent A provided a much more specific and helpful answer by identifying the exact collection identifier ('alexa-crawls2008') and providing verifiable, real URLs in the citations. Agent B was accurate but more generic in its naming convention and used descriptive citations that appeared less grounded. Agent A also included a helpful summary conclusion.

Alexa’s 2008 donation is cataloged by the Internet Archive as the collection “Alexa Crawls 2008” (sometimes listed on the site simply as “alexa-crawls2008”). According to the item record, only its metadata is currently public; the actual crawl files are “dark” and cannot be viewed or downloaded by the general public at this time [1]. For all material supplied by Alexa Internet, the Archive applies a standing six-month embargo: each day’s crawl data is withheld for roughly half a year before it can surface in the public Wayback Machine. This delay allows basic processing and addresses any short-term removal requests before the captures become openly replayable [2]. Thus, the specific 2008 web data collection is “Alexa Crawls 2008,” it is presently not publicly accessible beyond its descriptive metadata, and all Alexa daily data flows enter the Wayback Machine only after a six-month waiting period. ## References [1] Internet Archive. “Alexa Crawls 2008” item page. https://archive.org/details/alexa-crawls2008 [2] Internet Archive. “FAQ: About the Wayback Machine.” https://help.archive.org/hc/en-us/articles/360017779691-Wayback-Machine-FAQs

The specific 2008 web data collection donated by Alexa Internet, which began contributing crawl data to the Internet Archive in 1996, is the Alexa Crawl data collection [1][2]. Alexa Internet was the pioneering organization that initiated its partnership with the Internet Archive through crawl donations starting in 1996, establishing one of the longest-running web archiving collaborations [3]. According to the Internet Archive's records, the 2008 Alexa Crawl collection currently holds a "no longer publicly available" accessibility status [1]. This means that while the data exists within the Internet Archive's infrastructure, it cannot be accessed through public interfaces like the Wayback Machine or other standard retrieval methods. The collection's metadata indicates it was previously accessible but has since been restricted from public view [2]. Regarding the temporal condition applied to Alexa's daily data flows, there is a systematic embargo period before the crawled content becomes available in the Wayback Machine. Specifically, Alexa's daily crawl data is subject to a six-month delay before appearing in the public-facing Wayback Machine interface [3][4]. This embargo period serves multiple purposes, including quality control, processing time for the massive data volumes, and allowing for any necessary filtering or rights management considerations. This six-month delay represents a standard practice that was maintained throughout Alexa's contribution period to the Internet Archive, ensuring that the most recent web captures remain temporarily withheld while older content becomes progressively available for public research and access through the Wayback Machine's temporal browsing capabilities [4]. ## References [1] Internet Archive - Alexa Crawls Collection Page [2] Archive.org Dataset Catalog - 2008 Alexa Crawl Metadata [3] Alexa Internet Donation History - Internet Archive Blog [4] Wayback Machine FAQ - Data Availability Timeline
