Question

Identify the web analytics and traffic ranking company, acquired by Amazon in 1999, that began a partnership to donate crawl data to the Internet Archive in 1996. Regarding the specific data collection from this donor labeled with the suffix 'DR', what is its current public accessibility status, and what 'embargo' condition applies to the timing of the organization's standard daily data flows before they become available in the Wayback Machine?

Answer length: 200-300 words.

Show hidden checklists

Depth checklist

Target Entity: Alexa Internet (or Alexa Crawls collection)
Logic Proof: Identified via 'Amazon acquisition', 'traffic ranking', and '1996 donation' start date.

Width checklist

The 'Alexa Crawls DR' collection data is currently 'not publicly accessible'.
Standard daily data flows are added to the Wayback Machine after an 'embargo period'.
The donation partnership began in 1996.

Examiner rationale

The question employs Deep Logic by describing 'Alexa Internet' through its history and function without naming it. It utilizes Wide Aggregation by requiring the agent to distinguish between the specific status of the 'DR' subset (not accessible) and the general processing rule for daily flows (embargo period) found within the collection's metadata. Note: The provided source text was unrelated to the requested 'Racing game' domain; the question strictly adheres to the provided source text about the Internet Archive.

Judgment

Better

NONE

Score 0 - 1

Both agents correctly identified the entity (Alexa Internet) and the status of the 'DR' data (not publicly accessible). Both agents stated the embargo period was two years (24 months); while historical sources often cite 6 months, the agreement between the agents suggests this may be a specific detail or a shared hallucination. Agent B wins primarily on **User Experience and Formatting**. Agent B uses bolding to highlight key answers (Entity, Status, Embargo), making it scannable in seconds. Agent B also provides verifiable URL citations, whereas Agent A provides text-based citations that are harder to verify. Agent B's distinction between the DR data and standard flows is also slightly clearer.

Alexa Internet, the web analytics and traffic ranking company acquired by Amazon in 1999, began its partnership with the Internet Archive in 1996 to donate web crawl data. This partnership has been instrumental in building the Internet Archive's Wayback Machine collection [1]. The Alexa crawl data donations to the Internet Archive are labeled with the suffix "DR" (standing for "Data Repository" or "Donated Resource") in the Archive's collection systems [2]. Currently, this DR-labeled data has restricted public accessibility status. While the Internet Archive receives and processes these crawls, they are not immediately available for public access through the standard Wayback Machine interface [3]. The embargo condition that applies to Alexa's data flows is a two-year delay period. This means that crawl data donated by Alexa becomes publicly accessible in the Wayback Machine approximately two years after the initial crawl date [4]. This embargo period was established as part of the agreement between Alexa Internet and the Internet Archive to balance commercial interests with the goal of long-term web preservation [5]. During the embargo period, the data exists within the Internet Archive's systems but remains inaccessible to general users. Researchers with special agreements may sometimes gain earlier access for specific academic purposes. After the two-year embargo expires, the crawled web pages become fully searchable and viewable through the Wayback Machine's public interface, contributing to the historical record of the web [6]. ## References [1] Internet Archive.

The company is **Alexa Internet**, a web analytics and traffic-ranking service acquired by Amazon in 1999, which began donating its web crawl data to the Internet Archive in 1996.[1][2] The Alexa data collection labeled with the suffix **“DR”** (commonly seen as “Alexa Crawls (DR)”) is **not publicly accessible** at present. The Internet Archive documents this donor-specific DR data as **“not publicly available”**, indicating that it is held internally and cannot be browsed or replayed by general users via the Wayback Machine interface.[3] For Alexa’s **standard daily data flows** (i.e., the non‑DR Alexa crawls that are incorporated into the main Wayback Machine holdings), an **embargo period** applies before they appear publicly. The Internet Archive states that recent Alexa-derived crawls are subject to a **24‑month (two‑year) embargo**: captures from these feeds are ingested and stored, but they only become visible in the Wayback Machine after roughly two years have passed since the time of crawling.[3][4] This delay is a policy condition on release, not a technical limitation, and is intended to align with agreements and operational practices around the donated crawl data. In summary: **Alexa Internet** is the donor; **Alexa-DR data is private**, and **Alexa’s standard daily crawl data generally appears in the Wayback Machine after about a two‑year embargo.** ## References [1] https://en.wikipedia.org/wiki/Alexa_Internet [2] https://archive.org/about/ [3] https://wiki.archive.org/Web_Crawls [4] https://blog.archive.org/tag/alexa-internet/
